Installation Guide
Section 2 System Preparation
This section provides instructions for unpacking and installing the CombiFlash R
f
system. To prepare the system for operation, sequentially follow all instructions in sections 2.1 through 2.12.
2.1 Unpacking the Unit
The CombiFlash Rf is shipped in a single carton. Carefully unpack the shipment and inspect the contents. If there is any damage to the shipping carton or any components, contact the shipping agent and Teledyne Isco (or its authorized representative) immediately.
WARNING
If there is any evidence that the system has been damaged in shipping, do not plug it into AC power. Contact Teledyne Isco or its authorized representative for advice.
Compare the contents of the boxes with the enclosed packing slip. If there are any shortages, contact Teledyne Isco immediately.
2.2 Instrument Location
The CombiFlash Rf has a relatively small footprint, requiring about 1550 square centimeters (240 in
2
) of level bench space.
Ensure that the CombiFlash R
f
has at least 3 cm (1.25") of air space behind it for ventilation. Additional space may be required for solvent and waste containers.
Refer to Table 1-1 for environmental conditions and power requirements.
CombiFlash® Rf Installation Guide
2-2
WARNING
The system is heavy. Use a two-person lift to prevent injury.
Before making any connections to the CombiFlash Rf, place the system on the bench or in the fume hood where it will be operated. Temporarily position the system so you can access the back panel to complete the connections.
2.3 Connect Power
Ensure that the On/Standby switch below the touch screen panel is in the Standby position. Then, use the supplied IEC power cord to connect the CombiFlash R
f
to mains power.
WARNING
Mains power must meet the voltage, frequency, and amperage requirements listed on the serial number label.
2.4 Connect Solvent Lines
WARNING
Risk of fire ignited by electrostatic discharges. Never substitute the black tubing on CombiFlash systems. The black PTFE tubing (P/N 023-0503-06) is conductive. This tubing is required to dissipate static electricity.
CAUTION
To prevent damage or premature wear to the pump and internal valves, clean solvent should be used. The solvent should not contain any dissolved solids.
The CombiFlash Rf has four solvent inlet ports on the back panel: two A solvents and two B solvents. The system requires at least one A and one B solvent to form a binary gradient, and assumes that the B solvent is stronger than A. The second set of inputs allow you to form alternative binary gradients, or change the A or B solvent mid-run.
Accessory package (P/N 60-5239-006) includes several pieces to complete the solvent inlet connections.
Section 2 System Preparation
2-3
Figures 2-1 and 2-2 show the recommended connections when the user-supplied solvent container has a 38 or 45 mm opening (GL 38 or GL 45). Note that there are two different styles that can ship with the system. One styles includes a metal plate and larger opening on the cap (Figure 2-1), the other has no plate and a smaller opening on the cap (Figure 2-2).

The Solvent Level Sensing air line connects to the back panel with a compression fitting. This fitting must be airtight. To connect tubing using the compression fittings:
1. Slide the nut and ferrule onto the tubing as shown in Figure 2-1 or 2-2.
2. Fully insert the tubing into the threaded bulkhead fitting on the back panel of the system.
3. Finger-tighten the nut onto the threaded bulkhead fitting. This will seat the ferrule in the fitting.
Note
When using higher-density solvents such as dichloromethane (DCM), place the solvent container level with or above the CombiFlash Rf system. Placing solvent containers below the level of the Rf can contribute to decreased flow due to the high vapor pressure of DCM. This problem becomes more pronounced as the ambient temperature increases.
2.5 Connect Waste Lines
WARNING
Risk of fire or equipment damage. Failure to connect Waste Port tubing may allow organic solvents to pool in unsafe areas, possibly creating dangerous levels of flammable vapors.
WARNING
Risk of fire ignited by electrostatic discharges. Never substitute the black tubing on CombiFlash systems. The black PTFE tubing (P/N 023-0503-06) is conductive. This tubing is required to dissipate static electricity.
CAUTION
Elevated flammable vapor levels are possible. Ensure that the waste container is adequately ventilated, preferably by placing it in a fume hood.
The system has two waste outlets on the back panel: Diverter Valve waste and Inject Valve waste. You can route waste to a common collection container, or to individual containers.
CombiFlash® Rf Installation Guide
2-6
The Waste Level Sense uses air pressure to detect the liquid level in the common waste container. If using individual containers, use the waste level sense to detect the level of the Diverter Valve waste container. Under normal operating conditions it will fill faster than the Inject Valve waste container. Empty both containers at the same time to prevent overfilling the unmonitored container.
Accessory package (P/N 60-5239-006) includes parts to complete the waste connections. Figure 2-3 shows the recommended connections for user-supplied waste containers with either a 38 or 45 mm opening (GL 38 or GL 45). Note that there are two different styles that can ship with the system. One styles includes a metal plate (Figure 2-3), the other has a plastic plate with four small openings on the cap (Figure 2-4).
Refer to the steps in section 2.4 to connect the tubing to the system using the compression fittings. Then, complete the connections according to Figure 2-3 or 2-4.
If your connection hardware matches Figure 2-3, connect the Waste Level Sense line to the compression fitting in the center of the cap. Push the ends of the two black waste lines through the holes in the cap.
If your connection hardware matches Figure 2-4, push the three tubes through the cap. Push the stop on the Waste Level Sense tubing against the cap. This ensures that the Waste Level Sense tubing is far enough into the container to detect when it is nearly full.
Should the container not have a GL 38 or GL 45 opening, omit the use of the waste cap. Ensure the solvent tubes are secured so they drain into the waste container. Secure the Waste Level Sense air tubing so its outlet is at least two inches (5 cm) below the container’s maximum level.
Note
When using higher-density solvents such as dichloromethane (DCM), ensure that the waste container is no more than 3 feet below the supply solvent levels. Placing solvent containers above the system and waste containers on the floor may cause the internal check valves to open and allow solvent to flow through the system when in the standby state.

2.6 Optional External Gas
The CombiFlash Rf system has an internal air pump that provides compressed air for solvent and waste level sensing. Optionally, the system can deliver a compressed gas. Inert or other gases may be more suitable than air for some applications.
If ambient air is compatible with your solvents and waste, simply leave the Optional External Gas port open.
If you want to use a gas instead of air, connect user-supplied
1
/8" I.D. tubing to the Optional External Gas port. Connect the
other end to the user-supplied compressed gas. The external compressed gas should be dry, filtered, and regulated to 2– 5 psi (0.14–0.34 atm, 13.8 –34.5 KPa).
2.7 Connect and Route Drain Lines
WARNING
Risk of fire or equipment damage. Failure to connect drain lines may allow organic solvents to pool in unsafe areas, creating a potential for dangerous levels of flammable vapors. Improper draining may damage the instrument’s internal components.
The CombiFlash Rf has drain tubes extending from its top shelf and back panel. The tubes drain away any liquid spilled on the top shelf and the tray beneath the fraction collection racks. Route the end of this tubing to a suitable waste fluid collection container.
Note
It may be necessary to extend the drain tube. If so, splice the tubing with user-supplied tubing. The user-supplied tubing should have an inside diameter no smaller than the existing drain tubing, and must be compatible with the solvents used by the system. Route this extension tubing to the waste collection vessel.
2.8 Position the System
After completing the various connections, the system can be moved to its operating position. Turn the system so that the operator can access all of the front view features and controls (Figure 1-2). Use care not to damage the connections, tubing, and cables while moving the system.

2.9 Install Collection Tube Racks
Before beginning a run, you must load collection racks with tubes onto the system’s fraction collector tray.
Your system was shipped with two collection tube racks. The following tube rack sets are available:
60-5237-031 – Two racks for 16×125 mm test tubes (15.5 mL). Total tubes: 150.
60-5237-032 – Two racks for 16×150/160 mm test tubes (18 mL). Total tubes: 150.
60-5237-033 – Two racks for 18×150 mm test tubes (25 mL). Total tubes: 140.
60-5237-034 – Two racks for 18×180 mm test tubes (30 mL). Total tubes: 140.
60-5237-035 – Two racks for 25×150 mm vials (50 mL). Total vials: 60.
60-5237-040 – One rack for 500 mL French square bottles.
To load the racks:
1. Insert test tubes, vials, or bottles into the rack (Fig. 2-5).
CAUTION
Risk of broken glass or equipment damage. Do not load test tubes longer than the length listed on the tube size label.
2. While holding the rack with the tube size label visible (Figure 2-6), insert the racks into the system. Slide the rack in until you feel it drop into its seated position.
CAUTION
An incorrectly installed rack will cause the rack to be misaligned under the fraction collector arm. Misaligned racks might cause fractions to miss the tube opening or deposit in the wrong tube. Always ensure the tube size label is visible (that is, facing outward) and the rack is pushed in until it is seated.
Section 2 System Preparation
2-11
When you turn the power switch to on, the system will automatically detect the type of rack, and configure program settings accordingly. Later, in section 2.11.6, you can configure the maximum volume for each tube size.

2.10 Turn on Power
The system’s power switch is located just below the touch screen panel. Turn the switch to the ON position. The system will begin its startup routine which includes self diagnostics. The system is ready for operation when the PeakTrak screen is displayed.
2.11 Configure the System
Before operating the system, it should be configured for the desired operation. To configure the system, open the Configuration window by selecting Tools>Configuration from the PeakTrak menu.
The configuration window has two tabs: Instrument Configuration and Network Configuration. Adjust the following (sections 2.11.1 through 2.11.9) on the Instrument Configuration tab for the desired operation and then click OK to save the settings. Network Configuration settings are discussed later in Section 4, Remote Interfaces.
2.11.1 Solvents
When you installed the system, up to four solvents were connected to the back panel. This section of the Configuration window allows you to manage these solvents. To do so:
Note
The system is shipped with common solvent names already loaded. If your solvent names are listed in the solvent drop-down list boxes, skip steps 1 through 3.
1. Click the “Add Solvent” button.
2. Enter the solvent name and click the OK button.
3. Repeat steps 1 and 2 for all four solvents.
4. For the Solvent A1 drop-down list box, select the solvent name connected to the A1 Solvent Inlet Port. Repeat for Solvents A2, B1, and B2.
5. Select the “Enable solvent level sensing” check box to enable this feature (recommended). Clear this box to disable this feature.
Section 2 System Preparation
2-13
The solvent level sensing feature will monitor solvent usage to minimize the risk of running out of solvent during a purification run. The system compares the volume required for a purification run with the estimated volume in the solvent container and alerts you when there is not enough.
6. If using the solvent level sensing feature, enter the Minimum Solvent Level (density dependent) as a range in centimeters.
To understand this range, consider that dichloromethane is more dense than hexane. If the selected range is 2–4, the system triggers an alert when the dichloromethane level falls to about 2 cm above the weighted filter. At the same selected range, the system would trigger an alert when the hexane falls to about 4 cm above the weighted filter.
2.11.2 General Settings
CombiFlash Rf Name (optional) – Use this option to name your system. The name will appear in operational displays and run summaries. This feature is useful when your laboratory has more than one CombiFlash R
f
system.
Language – Select the desired language from the drop-down list box.
2.11.3 Vapor Limit
The system has an internal vapor sensor that detects vapors present in the immediate atmosphere. When the limit is exceeded, the CombiFlash R
f
will shut down to avoid a
hazardous condition.
Teledyne Isco recommends using the default setting of 25. This value represents an organic vapor level slightly above the ambient vapor level of a well-ventilated laboratory.
A setting below 25 could cause random alarms without significant vapors present. If PeakTrak displays a Vapor Limit alarm while the Vapor Limit is set at 25, perform the following checks on your laboratory and the instrument:
• Ensure that no open containers or spills of organic solvent are in close proximity to the system.
• Ensure that the system is located in a well-ventilated area.
CombiFlash® Rf Installation Guide
2-14
• Ensure that there is no visible solvent leakage from the system.
If PeakTrak continues to display the Vapor Limit alarm after you have made these checks and corrected any problems found, it is likely that organic vapors are present in the ambi­ent environment of your laboratory. In this case, increase the setting of the Vapor Limit. Settings greater than 25 are appro­priate for laboratory environments with a somewhat elevated background solvent vapor concentration, representing a safe setting, but one with a reduced margin for error.
2.11.4 Automatically Print Report at End of Run
If this option is enabled, the system will print a report at the end of each run.
Note
This option requires the system to configured for network operation and a connection to a printer on the network. Network settings are discussed in Section 4, Remote Interfaces. Do not select this option for these initial installation steps.
2.11.5 Enable Run Length Extension
When enabled, this option automatically extends the run if a peak is eluting at the end of the maximum %B gradient. This ensures that a late-eluting peak fully comes off the column and is collected.
An automatic run extension is a five-minute isocratic hold added to the end of the run’s maximum %B gradient profile. During the extension, the system continues to pump the maximum %B solvent mixture. Should the system still detect a peak after an extension, the system will add another, up to a maximum of three extensions.
Occasionally, compounds might come off the column once the %B returns to the minimum value at the end of a run. If the Run Length Extension is enabled, it will automatically extend the run one time to clear the column and plumbing of any remaining material.
Section 2 System Preparation
2-15
Figure 2-7 Automatic Run Extension Examples
Figure 2-7 illustrates the possible run extensions. The original method was programmed to rise to the maximum %B over seven minutes, hold for two minutes and return to the minimum %B for a final minute. At nine minutes, a peak was eluting. The system extended the run, holding the %B at the maximum level for another five minutes. This also occurred at fourteen and nineteen minutes, resulting in the second and third extensions. At 24 minutes, the %B solvent strength returned to zero. Before the final minute elapsed, more compound was detected, causing the system to extend the run for a final five minutes at the minimum %B.
2.11.6 Set Default Tube Volumes
Click this button to open a window from which you can set the default volume of the collection tubes. You can increase or decrease these values to set the desired default volume collected in each container. Just be sure you don’t overflow the containers by exceeding their capacity.
The system will automatically advance to the next tube when this default volume is met in each tube. Keep in mind that advanced method settings (discussed in Section 3 and the on-line help) may override this default setting. During a run, other factors such as automatic tube advances for detected peaks will affect collected volume.
2.11.7 Set Date/Time

To prevent unauthorized time changes, this feature is password protected. The system is shipped with the password set to combiflash. Use the Tools>Set Password menu command to change this password for greater security.
2.11.8 Default Run Units
Run units are displayed along the X-axis of the chromatogram. Select Time (in minutes) or Column Volumes. A column volume unit is the time it takes to pump enough solvent to exchange the volume held by the column. The duration in minutes will vary according to the column media and size, and the flow rate.
2.11.9 Gradient Method
Select the standard gradient type (Figure 2-8).
Linear – The system gradually mixes solvents A and B from the last programmed %B until it reaches the next programmed %B. This method connects the inflection points that define the gradient with a straight line.
Step – The system holds each %B value until it reaches the next programmed %B. Because the system holds the %B values, the changes at each new value are nearly instantaneous, producing a stepped appearance on the plot area.
Isocratic – The system holds the initial solvent mix for the entire run.
Figure 2-8 Gradient types

2.12 Prime the Solvent Lines
Before the first use, the system should be primed. Ensure that the solvent containers are filled, then:
1. Select the “Tools>Auto prime” menu command.
2. Select the desired A and B solvents from the drop-down list boxes.
3. Click the Play button to start priming the system.
The system pumps 100% Solvent B through the system and out the Waste port, and then repeats with 100 % Solvent A. (This B-A order leaves the internal lines filled with solvent more appropriate for the beginning of a purification run.)
Note
When priming the first time, inspect the solvent and waste connections to the system. If any leaks are observed, click the Cancel button to stop the Auto Prime. Correct the leak by tightening the fitting an additional
1
/4 turn, and then restart the Auto
Prime from step 1.
To advance to the next Auto Prime step, you can click the Fast Forward button. The Auto Prime window closes when finished.
After Auto Priming, the system is ready for operation (Section 3).
Note
Use Auto Prime for quick solvent changes by pumping a fixed amount of solvent through the waste fluid path at 100 mL/min. For more advanced priming functions such as varying the flow rates, fluid paths, etc., or to purge the system with air before changing between normal and reversed phase solvent systems, use the Tools>Manual Control option.

Installation Guide
Section 3 Operation
This section provides abbreviated operating instructions for the CombiFlash R
f
. For complete instructions, refer to Help
menu option from PeakTrak’s main menu.
3.1 Sample Preparation
Before starting a run, consider how the sample will be introduced to the column media. This section discusses three methods: liquid injection, solid sample cartridges, and preloading the sample on the column.
3.1.1 Liquid Sample Injection
If the sample is soluble in the starting mobile phase, it can be prepared as a solution and injected onto the column when prompted during the purification run.
3.1.2 Solid Samples
Some compounds are not soluble in solvents that are compatible with the chromatography. In addition, the compounds may have very limited solubility in any solvent, resulting in sample volumes that are impractical for good chromatography. The solution in this case is solid sample introduction. Here the reaction mixture or dissolved sample is mixed with the same media in the chromatography column.
Some samples of this type may be simply dissolved and placed into a prefilled cartridge. You can then use the cartridge immediately, or dry it by vacuum before placing it on the system.
Other samples may need more care. Typically you would create a mixture of 20% sample load to media (w/w). Then dry the mixture under conditions that will drive off the solvent without affecting the compounds of interest. These compounds
CombiFlash® Rf Installation Guide
3-2
remain bound to the media. Once dried, pour the media/sample mixture into an empty cartridge.
To prepare an empty solid sample cartridge:
1. Ensure the empty cartridge has a bottom frit.
CAUTION
Missing frits may cause equipment damage, UV detection problems, or increased maintenance. Frits prevent solids from entering the fluid path.
2. Prepare the media and sample:
a. Dissolve your sample in a minimal amount of a suitable,
volatile solvent.
b. Place the media into the solvent. If using silica gel, a
particle size of 40–60 µm (240–400 mesh) is recommended. The amount of silica required is about four to five times the mass of your sample.
c. Agitate the solvent for a moment to allow the sample to
adsorb to the silica.
d. Remove the solvent with a suitable method, such as
rotary evaporation.
3. Load the media and sample mixture into the cartridge. Tap the cartridge on the benchtop to settle the mixture.
4. Place a frit on the top of the cartridge. Force the frit down against the mixture using the plastic plunger.
5. Wipe any residual powder inside the neck of the cartridge.
Empty solid sample cartridges also allow a variety of adsorbents, such as diatomaceous earth, boiling chips, cotton balls, or paper wipes. Even with alternative adsorbents, always use top and bottom frits to prevent fluid path problems.
After you have prepared the pre-filled or empty cartridge, place the solid sample cartridge on the system:
1. Attach the desired adjustable cartridge cap to the system.
2. Align the cap and cartridge and push them together.
3. Rotate the cartridge
1
/4 turn so that the cap will hold the
cartridge.
Section 3 Operation
3-3
4. Press the tab on the cap and push the plunger into the cartridge until it rests against the top frit.
5. Release the tab on the cap. Note that the opposite end of the tab secures the cartridge.
6. Load the solid sample cartridge with cap on the sample injection port.
3.1.3 Preloading on Column
You can load the reaction mixture or sample directly onto the column, sometimes called “direct” or “dry” loading.
Note
If using this method, use care to ensure that a column equilibration does not wash away the sample. Bypass the column equilibration at run time by selecting “Preload on column” as the sample Loading Type. Refer to Section 3.3 for more details.
3.2 Loading a RediSep Rf Column
To loa d a RediSep Rf column:
Note
For best results, always use RediSep Rf columns. The system will not automatically detect other columns, including non-Rf RediSep columns. The system also limits the maximum operating pressure to 50 psi when the column is not detected.
1. Select a RediSep Rf column. The on-line help includes a column selection guide that can assist you in selecting a
stationary phase media and column size.
2. Raise the injection valve and insert the column into the top column fitting. Note that the column fittings are keyed to ensure the correct flow direction.
3. Slowly lower the injection valve while aligning the bottom column fitting. The spring-loaded injection valve will hold the column in place.
4. To seal the column fittings, give the column a slight twist (
1
/4 turn).
CombiFlash® Rf Installation Guide
3-4
Note
After loading a RediSep Rf column, the system will use RFID technology to automatically detect the media type and column size. PeakTrak displays the detected column size on the Main and Method Editor windows. If the system does not detect the column, manually select the column media and size.
3.3 Start a Default Method
After completing the installation steps in Section 2, preparing the sample, and inserting the column, you are ready to perform a run with the default method. The system’s default methods are factory-set with run parameters typically used by chemists. Default methods are optimized for the use of RediSep R
f
columns. The default settings will:
• equilibrate the column
• collect all fluid in the fraction collector rack
• differentiate between UV vs. non-UV absorbing fluid and place the fluids into separate tubes
• cut UV absorbing peaks based on slope detection or level threshold.
To start the run from the PeakTrak Main window:
1. Enter a sample name. If you choose not to, PeakTrak will enter the date and time as the sample name when you start the run.
2. Review the PeakTrak Main window settings. If you want to change any settings, refer to the Editing a Method on-line help topic.
3. Click the Play button.
4. Select the sample Loading Type from the list. This Loading Type should support the sample preparation you chose in Section 3.1. Possible sample loading types are:
Section 3 Operation
3-5
Cartridge w/ (with) pause – Select this option if you intend place the sample into a solid sample load cartridge, but have not yet prepared the sample. When you click the run button, the system will perform a column equilibration and then wait while you prepare the cartridge. After you have placed the cartridge on the system, click OK to continue with the run.
Cartridge w/o (without) pause – Select this option if you have prepared the sample and placed it into a solid sample load cartridge. The system will proceed automatically until the end of the programmed run length.
Liquid Inject – Select this option if you have prepared a liquid sample and plan to manually inject it into the injection port after column equilibration.
Preload on column – Select this option if you have preloaded the sample on the column. The system will skip column equilibration so that the sample will not be flushed from the column before the run.
5. Review or update the Start Rack and Start Tube.
6. Review the Minimum Run Requirements. The system will report the estimated solvent volumes, expected waste, collection tube usage, etc. You can use this information to verify that there will be enough solvent to complete the run, the waste volume does not exceed the collection container’s capacity, and whether or not more tubes will be required during the run.
Note
The system estimates the solvent volumes by monitoring the solvent level in the container and the known usage rate. The system continues to refine this estimate during operation.
Note
If the waste level sensing tube is inserted correctly into the waste container, the system automatically will suspend operation before an overflow condition might exist. To prevent the run from being suspended before completing the run, ensure that the container will hold the expected waste volume.
CombiFlash® Rf Installation Guide
3-6
7. Click OK and the run begins. The system responds according to the sample Loading Type you selected in step 4.
If you selected Cartridge w/ pause, the system equili­brates the column with the starting %B and then waits while you prepare the solid sample load cartridge. Place the cartridge on the system and click OK to continue.
If you selected Cartridge w/o pause, the system equili­brates the column and immediately starts the separation.
If you selected Preload on column, the system skips the equilibration and immediately starts the separation.
If you selected Liquid, the system equilibrates the column and then waits. When instructed, perform the following steps:
a. Place the injection syringe on the injection port.
b. Slowly force the liquid into the injection port.
c. Chase the first injection with a second injection solution
of at least 0.25 mL. The chase solution can be the starting mobile phase or diluted sample mixture.
d. Click OK to continue the run.
3.4 During the Run
You may allow system to proceed with the run while monitoring the progress on the PeakTrak main window. If desired, gradient parameters may be modified during the run. (See the Real-time Gradient Editing on-line help topic.)
As the run progresses, the absorbance trace is drawn on the Gradient Plot area. The separation or purification continues until the end of the run defined by the run length setting.
Section 3 Operation

3.4.1 Run Control Buttons
You clicked the Play button to start the run. During the run, other run control buttons are active.
Pause — The Pause button holds the %B at the current value while the system continues to operate (sometimes called an isocratic hold). Note that pausing the run extends the run length. While in the Paused state, you can resume the run by clicking the Play button, or stop the run by clicking the Stop button. If you resume the run, the system continues with the gradient curve at the %B when the system was paused.
Stop — This button suspends the entire run. Unlike the Paused state, the pump, peak detection, and fraction collection will not operate. While stopped, you can save the run data by selecting the File>Save Run as PDF or Save Run as Text from the menu, end the run by clicking the Rewind button, or resume the run by clicking the Play button.
Next Tube — This button advances the fraction collector to the next tube position. This allows you to conveniently collect elute of interest in a new tube.
Note
When you click the Next Tube button, the system immediately marks the tube advance on the chromatogram. However, the system delays the movement of the drop former over the tubes. This delay accounts for the volume held in the tubing between the detector and the drop former, sometimes called the “delay volume.” It is important to remember that the chromatogram displays activity in real time while the fraction collector activity lags behind. The duration of this delay will vary with the flow rate.
Rewind — This button is active when the system has completed the run, or if the run was stopped by clicking the Stop button. The Rewind button returns you to the Main window with the current method.
If you have stopped the run before its programmed run length has elapsed, clicking the Rewind button changes the current method to the new, shorter run length. This modi­fied method is ready for the next run, or can be saved for future runs.
CombiFlash® Rf Installation Guide
3-8
Fast Fo rwar d — Click this button to jump to the next step of a run.
Once you have started a run, the system performs several steps. The first step is to deliver solvents using the pro­grammed gradient for the entire run length. When this step is complete, the system will purge the column with air and clean the injection valve. Clicking the Fast Forward button will cause the system to skip any remaining time in the current step and advance to the beginning of the next step. Unlike the Rewind button, the clicking the Fast Forward button to complete the run will not modify the current method’s run length setting.

Section 4 Remote Interfaces
This section provides instructions for controlling the CombiFlash R
f
system through a remote interface. The system can be accessed by several personal computers through a corporate network, or by a single personal computer (PC) through a direct connection.
4.1 Network Configuration
Note
The procedures described in this section will require assistance from your network administrator. Contact your Information Technology department before proceeding.
The system has a factory-assigned IP address— 192.168.1.51. In many cases, this address must be reconfigured for use on a corporate network. To reconfigure the IP address:
1. From the touch screen panel, select the Tools>Configuration menu command.
2. The Configuration window has two tabs. Select the Network Configuration tab.
3. Select the Network Type. The options are “Static IP” and “DHCP”.
Static IP – If you select “Static IP,” configure the IP Address, Netmask, and Gateway with the information pro­vided by your network administrator.
DHCP – Before considering DHCP, review the three follow­ing questions with your network administrator. If you can answer Yes to all questions, then DHCP is an option for your system.
CombiFlash® Rf Installation Guide
4-2
Is it possible to assign a static IP address based on the MAC address of the instrument? (Administrators may
use this method to assign static addresses through the DHCP server instead of directly on the instrument, simplifying the management of static IP addresses within the organization.)
Note
A label on the system’s back panel lists its MAC Address. You also can find the MAC Address on the Help>About PeakTrak window.
Can the DHCP server support an infinite lease for the instrument?
• Can the DHCP server automatically update the DNS records after the IP address is given to the instrument?
If you select “DHCP,” enter a unique Instrument Name. The name will be sent with the DHCP request and will be used to update the DNS settings. This name would allow you to assign an Instrument Name such as “My_Rf.” Users would then access the instrument through the address “http://My_Rf.”
4. Click the OK button to save the settings.
5. Confirm that your network administrator has completed any necessary network changes to support the system.
6. Locate the CAT5 connection cable (P/N 480-6545-01) in the accessory package. Insert one end into the Ethernet port on the back panel. Connect the other end of the cable to your network access port.

Section 5 Maintenance
5.1 Preventive Maintenance
The system requires preventive maintenance for safe and reliable operation. Refer to the schedule below for the minimum periodic maintenance requirements.
As Needed – Perform these tasks as conditions require:
• Cleaning (section 5.2).
• Quick flow cell cleaning when recommended by a system alert message (section 5.4.2).
Every Run – Allow the separation run to finish with a high percentage of solvent B to flush residual compounds from the column, internal tubing, and flow cell. Refer to section 5.4.1.
Nightly – Log off the system (File> Log out) and place the
On/Standby switch in Standby.
Monthly – Perform these tasks at least monthly, more frequently if conditions warrant:
• Tubing Inspection (section 5.3).
• Collection rack and tray cleaning (section 5.2.1).
• Monthly flow cell cleaning (section 5.4.3).
5.2 Cleaning
To clean the exterior surfaces, use distilled water with a mild detergent. Use isopropyl alcohol for tougher stains.
On printed areas such as labels, avoid rubbing vigorously or using aggressive solvents like acetone. Each will ruin the printed text.
CombiFlash® Rf Installation Guide
5-2
CAUTION
Do not immerse the instrument in a water bath. The instrument is not watertight and this action could damage the internal electronics.
5.2.1 Collection Rack and Tray Cleaning
WARNING
Risk of fire or equipment damage. Unclean collection racks and tray might inhibit their conductive properties. The racks and tray must be kept clean to dissipate static electricity.
The collection tube racks and tray are made of conductive plastic. Dirt, film, or coatings might prevent their ability to dissipate static electricity. To avoid problems that possibly result from an electrostatic discharge, clean the racks and tray monthly. Use distilled water with a mild detergent. For tougher stains, use isopropyl alcohol.
5.3 Tubing Inspection
WARNING
Risk of fire or equipment damage. Faulty tubing, fittings, and drains may allow organic solvents to pool in unsafe areas, creating a potential for dangerous levels of flammable vapors. Improper draining may damage the instrument’s internal components.
Perform a tubing inspection monthly:
1. Visually inspect the solvent, waste, and drain tubing. The tubing must be free of any damage, kinks, or deterioration. Fittings should show no signs of leaks.
2. Test the collection tray drain and top shelf drain by connecting a vacuum or air supply source to the outlet end of the drain tubes. Then, verify the presence of such vacuum or air supply source on the drain hole (Figures 5-1 and 5-2).
Correct any deficiencies before returning the instrument to operation.
Section 5 Maintenance

5.4 Flow Cell Cleaning
5.4.1 Post Separation
As a preventive measure, all default column methods finish the separation run with a high percentage of solvent B (Figure 5-3). This brief time (two to three column volumes) of strong solvent flushes residual compounds from the column, flow cell, and internal tubing.
Figure 5-3 Default post-separation column and flow cell flush
Avoid skipping the flush by stopping the run after the last compound elutes. Skipping the flush may cause residual compounds to build up and crystallize, which might result in:
• cross contaminating later separation runs
• higher operating pressures
• reduced flow cell lamp energy
• a noisy baseline on the absorbance trace
• frequent messages recommending flow cell cleaning (Figure 5-4).
Allow the separation run to complete the full default column method. If the conditions above occur repeatedly, consider extending the flush time in the default column methods (Tools>Edit Defaults).

CAUTION
When using methanol as solvent B with silica column media, do not pump more than 50% solvent B. Higher percentages of methanol might break down the silica structure, possibly causing obstructions in the flow path.
5.4.2 Quick Cleaning when Recommended
When the lamp energy is lower than normal, the system will recommend flow cell cleaning (Figure 5-4) before starting a separation run.
Figure 5-4 Flow cell cleaning message
When the system displays this message you can:
Cancel Run (recommended) – Click the Cancel Run button so you can perform a quick cleaning described in the following steps.
Continue Collect All – Click this button to ignore the message. Because the peak detection operation might be impaired, the system automatically collects all fluids to avoid diverting compounds of interest to waste.
Help – Click this button to display the flow cell cleaning on-line help topic.
To perform a quick cleaning:
1. After clicking the Cancel Run button, select the Tools>Manual Control menu option.
2. From the Manual Control window (Figure 5-5), note the Raw Lamp Energy level at 254 nm. The Raw Lamp Energy gauge has three ranges: red, yellow, and green.
CombiFlash® Rf Installation Guide
5-6
Figure 5-5 Raw Lamp Energy Gauge
Red – lamp energy is obstructed to a degree that the system might not reliably detect peaks. If you attempt to operate the system, peak collection will be forced to collect all. This prevents diverting desired compounds to waste.
Yellow – lamp energy is partially obstructed and the peak detector performance might be impaired. The system can be operated although the absorbance trace might appear noisy. Yellow might be a normal indication for systems with flow cell windows stained by compounds.
Green – lamp energy is sufficient to detect peaks up to 3.0 Absorbance Units.
3. Remove the column and insert a bypass tube between the upper and lower column mounts. A bypass tube (P/N 209-0165-46) can be found in the accessory kit (P/N 60-5239-006).
4. Set the Flow Rate to 40 mL/min (Figure 5-6).
5. Select Through column for the Valve Position option.
6. Select Next for the Pump into Tube # option. By pumping into a collection tube, the diverter valve is also cleaned of any residue during this operation.
7. Click the Prime B button to pump 100% Solvent B through the bypass tube and into the collection tubes.
Section 5 Maintenance
5-7
Figure 5-6 Manual Control Settings - Quick Cleaning
Note
Pumping solvent B at a moderate flow rate (25 to 45 mL/min) over time will usually solubilize obstructions. Generally, the recommended solvent is the highest polarity solvent you have recently used (solvent B).
8. Monitor the Raw Lamp Energy gauge. As the system pumps solvent, the raw lamp energy should gradually improve. Pump solvent for two to five minutes or until the indicator reaches the far-right of the green range.
When the indicator is in the yellow, the lamp energy and flow cell are ready for the next run. However, continuing the cleaning for greater raw lamp energy should reduce the frequency of flow cell cleaning messages (Figure 5-4).
If after five minutes the indicator is still in the red range, repeat the cleaning steps using an alternative solvent (Table 5-1). Or, complete the steps in the Monthly Flow Cell Cleaning procedure (section 5.4.3).
Note
If the numerical values of the Raw Lamp Energy (Figure 5-5) do not change, or if the first number remains at zero, contact Teledyne Isco’s Technical Service department.
CombiFlash® Rf Installation Guide

Table 5-1 Suggested Flow Cell Cleaning Solvents
a
Solvent Description
Methanol Miscible with most LC solvents. Methanol will force other
solvents through the system so they will not interfere with the next sample. It breaks down the tertiary structure of silica and allows it to flush through.
Acetone Common organic solvent with high dissolving properties.
Acetone absorbs UV light at 254 nm. Therefore, the Raw Lamp Energy gauge will always read red when acetone is in the flow cell. After pumping acetone, pump a different solvent through the system to remove the acetone and read the Raw Lamp Energy gauge.
Dichloromethane (DCM)
Effective at solubilizing organic molecules.
Dimethylsulfoxide (DMSO)
Strong solvent that will clear organic sample.
Dimethylformamide (DMF)
Strong solvent if other solvents do not produce the desired results.
Tetrahydrofuran (THF)
Strong solvent.
Water/DMF/ methanol
A 50/25/25 solvent mixture effective in clearing some obstructions.
Water/DMF/ Acetic Acid
30/30/30ml solvent mixture effective in clearing some obstructions.
Mildly acidic aqueous solution
0.5M acetic acid in distilled water can be used to clear samples that are not removed by organic solvents.
Mildly basic aqueous solution
A dish-type detergent solution can wash through particulates not picked up by the acidic solution. The emulsification effect of detergent is an effective tool as well to help wash through oily samples. Follow the detergent with several minutes of clean, distilled water.
a. Recent synthesis solvents should also be considered.

5.4.3 Monthly Flow Cell Cleaning
Perform this procedure as part of your scheduled preventive maintenance, or when Quick Cleaning As Required (section
5.4.2) does not improve the lamp energy.
1. Remove the column and insert a bypass tube between the upper and lower column mounts. A bypass tube (209-0165-46) can be found in the accessory kit (60-5239-006).
2. From the menu, select Tools>Manual Control. This opens the Manual Control window.
3. Set the Flow Rate to 40 mL/min (Figure 5-6).
4. Select Through column for the Valve Position option.
5. Select Next for the Pump into Tube # option.
6. Place the B1 Solvent inlet line into a reservoir of methanol, acetone, or a strong solvent that readily dissolves residual sample material.
7. Click the Prime B button to pump 100% Solvent B through the bypass tube and into the collection tubes.
8. After three minutes, click the Stop button. Allow the system to stand for at least six hours. Overnight is recommended.
9. Return the B1 solvent line to the original solvent container.
10.Perform the Quick Cleaning as Required (section 5.4.2) and monitor the Raw Lamp Energy.
If the lamp energy is in the green or yellow range, return the system to operation. If the lamp energy is red, contact Teledyne Isco’s Technical Service department for assis­tance.
