CHAPTER 1
1.1 Features of the Probot Micro Fraction Collector
Introduction
The LC Packings Probot Micro Fraction Collector is a robotic fraction collector that can be used to collect samples from a capillary HPLC or CZE system and deposit onto targets such as a MALDI mass spectrometer target, a PVDF membrane (e.g. for protein sequencing), a nitrocellulose membrane or a micro titer plate.
The heart of the unit is a robotic table that can be positioned in the X, Y and Z directions by means of 3 stepper motors under the control of a personal computer and the Carrier software package. The table can be driven in either a linear or circular motion and the distance from point to point, the time spent at a point and the speed of movement are readily programmed. A reference position is defined by the system, and the user can select a starting position as well as a park position (where the plate should be moved to during rest periods). Various adapter tables are available for carrying the different targets.
When the Probot Micro Fraction Collector is employed with the µCarrier software, the system provides the following features:
High precision X-Y-Z movement of the table – any position within the working
area can be programmed with a resolution down to ± 2 µm.
Smooth operation – results in no vibration of the needle, which is essential for
nanoliter spotting and smooth UV-detection.
Short capillary connection between outlet and needle – extremely low dwell
volume.
Fully automated adding of matrixes or make-up solutions – simplifies spotting
Capillary/Nano LC fractions onto MALDI targets. The matrix can either be added before the needle (µ-Tee) or co-axially at the needle tip (standard Tee).
Dual-Collection mode - a fraction can be split between two sample carriers
simultaneously, i.e., a MALDI/MS target and a well plate, or a PVDF membrane. The split ratio is programmable and all sample vessels, including 1536 well plates can be used.

The Probot Micro Fraction Collector is supplied with a µ-Tee connection (FIGURE 1-1). The lower end of the needle Tee holds a hollow needle in which a fused silica capillary is mounted, the horizontal inlet is used to add reagent (e.g. a matrix solution) to the sample using the Dosage Module and the upper connection is connected to the LC/CZE system (e.g. the capillary flow cell outlet of the UltiMate UV detector).
1-2 D960R3 User’s Manual Probot
Introduction
The following options are available for the Probot:
Manual Control Unit – allows for moving the sample table manually. Dosage Module – The dosage module consists of a 4 way rotary valve with a
syringe drive and a 100 L syringe. It can be used in different modes:
- Continuous Flow Mode – a matrix solution/reagent is added on a
continuous basis (nL/min to µL/min).
- Dosage Mode –a user-defined volume is added to each sample.
- Wash Mode – the needle can be entirely flushed to avoid crystallization of
the matrix solution.
µ-Tee for Matrix Addition – allows for adding the matrix solution before the
needle directly in the Nano flow path (default configuration).
Standard Needle Tee – allows for adding the matrix solution through the
hollow needle co-axially at the needle tip (supplied with the instrument).
Camera Option – A camera kit (P/N 160590) is available which allows for easy
monitoring of the needle and target(s) in conjunction with µCarrier 2.x or a standalone monitor.
Pipetting Option – The pipetting option (P/N 161072) allows for pipetting from
a source plate (e.g. a well plate) to a destination plate (e.g. MALDI target). It consists of a Teflon tube (45 cm, I.D. 250 m) with fittings and a fused silica capillary (15 cm, O.D. 280 m, I.D. 100 m).
Waste Removal Option allows the user to remove undesired portions of the
separation (‘waste’) without the need to spot them onto the target. A vacuum can be applied to draw the solvent into a waste container.

Installation and Getting Started
2.6.2 Design of µCarrier
The Carrier Liquid Handling Application Designer Software (V2.0) is built around the following three basic components:
The sample carrier – represents the target (e.g. a MALDI target or a microtiter
plate), which is used. It describes the number of spots on this target and their position relative to each other.
The tray – represents a number of sample carriers and there positions on the
table. It is required to define the position of every spot on the tray. By aligning the sample carriers, every spot on the MALDI targets is defined with respect to the exact X, Y and Z coordinate relative to the needle of the Probot.
The application – represents all ‘rules’ (tasks) required for spotting. A
collection of spots is grouped and these groups are used within the different tasks. Every spot is defined by its X, Y and Z coordinates, so each spot can be found individually. This allows you to use your MALDI targets in any way you want (e.g. you can collect two runs on one MALDI target or one run on two MALDI targets). The application file holds the parameters for the sample carriers, the tray and the tasks.
For each component a special wizard assisted ‘Editor’ is available.
2.6.3 The Editors and Wizards
For the ease of use µCarrier provides various wizards and editors for the design of the sample carrier, the tray and the application:
Sample Carrier Alignment Wizard – Section 2.7.3 Sample Carrier Wizard – Section 2.8.1 Sample Carrier Editor – Section- 2.8.1 Tray Setup Wizard – Section 2.8.2 Tray Editor – Section 2.8.3 Fractionation Application Wizard - Section 2.8.4 Application Editor – Section 2.8.4

2.7.3 Alignment of the Sample Carriers
The following procedure needs to be performed to define the exact position of the sample carriers on the table relative to the needle tip (including the ‘spotting height’). During this procedure the table is moved manually to certain reference positions and their coordinates (X, Y, Z) will be stored in the Once this procedure has been performed successfully, this setup can be used as long as the hardware has not been modified (e.g. the needle has been replaced or bent).
Note: The proper alignment is essential to achieve optimal spotting performance.
Once the hardware has been modified (e.g. the needle has been replaced or bent or a different table is used) or the Probot has been moved, it is necessary to repeat this procedure.
If the tray definition includes the exact positions of all sample carriers relative to each other (e.g. multiple sampler carriers of the same type in predefined positions), the µCarrier software needs only one spot as reference position to align all carriers in one step. If the tray definition does not provide the exact (relative) X and Y positions, the alignment has to be performed for each sample carrier individually.

g) Finally, adjust the table height (Z axis) so that the needle tip just touches the
surface of the target. This adjustment is the ‘spotting height’ which will be used during spotting for all carrier positions (selected in step b).
Note: The optimal distance of the needle tip to the carrier surface depends on
your application parameters (e.g. the LC flow rate, the matrix flow rate, etc.).
h) Once all axes are moved to their proper positions confirm by Next, and then
wait for the message box telling you the sample carriers have been aligned (FIGURE 2-18). This can take a few seconds. When finished, the table will move to home position

2.8 µCarrier – Basics Steps

The following sections discus the basis steps of the µCarrier software. We show how to
Create a New Sample Carrier using the Sample Carrier Wizard – Section 2.8.1. Create a New Tray using the Tray Setup Wizard – Section 2.8.2. Modify an Existing Tray Setup using the Tray Editor – Section 2.8.3. Create a New Application using the Wizard – Sect. 2.8.4. Control the Table Position – Section 2.8.5. Measure the Column (X) and Row (Y) Distance – Section2.8.6.
The various steps are explained in detail using the following typical application example:
A table with six rectangular MALDI target plates with 24 x 24 spots is used
for the fractionation of a NanoLC run. The LC flow rate is 300 nL/min, the distance between columns and rows is 1.45 mm and the spot diameter is 1 mm.
The fraction collection time is 20 sec. A MALDI matrix solution is added at a flow rate of 1.2 µL/min (= 4 times the
LC flow rate) along with the fractionation of the mobile phase.
The start of the fractionation is synchronized with the injection of the UltiMate
Capillary HPLC system and the start signal is delayed by 5 minutes.
Between the runs the needle should remain in a wash vial to prevent
crystallization of the matrix solution. Dispensing 10 to fractionation will prevent any matrix dilution.
All available spots will be used.
The application discussed here corresponds to the application that was used to shown in the ‘µCarrier – First Steps’ section. Please refer also to the user’s manual of the
Carrier software for more detailed information.

Note: The shape selected does not need to match exactly the shape of the
actual spot(s) of the MALDI target. Some manufacturers use triangular spot shapes or round and rectangular shapes on the same MALDI target. Choose the shape that fits best with your target. Circular shape is a safe choice to begin, because the droplets created have also a circular shape.

User’s Manual Probot D960R3 2-35
Installation and Getting Started
FIGURE 2-37 The Fractionation Application Wizard – Fraction Control Mode
The following modes are available:
Time – The fractionation is controlled by time. The intervals are specified in
seconds and can be as low as 4 seconds. Time control is the most commonly and safest control mode. This control mode allows also for fractionation by a time table.
External –Input signals control the fractionation (e.g. peak start and peak end).
A CHROMELEON program can be designed to generate to generate such signals on the Ultimate Micropump while the UV signal is used for peak detection. This allows for collecting of peaks only.
Manual – This control mode requires input of the operator. The operator
determines by manual input (mouse) the when a peak starts or ends. This requires that the operator monitors the entire chromatographic run and provides the right signal with each peak.
Note: In time control mode the entire chromatogram is collected, e.g. all peaks
and ‘waste’. With external and manual control, the ‘waste’ can be discarded. Make certain that the peak detection parameters are properly set to avoid the possibility that peaks are treated as ‘waste’ in external control mode.
The next step is to specify the number of LC runs (injections) and to define in which way the available sample carriers are used (e.g. one sample carrier per injection or LC run). FIGURE 2-38 shows the three basic possibilities and which option the appropriate is depending on the requirements:
One injection - The LC run (‘sample’) is collected in one group. This group can
use all spots of all sample carriers.
Multiple injections, optimal use of spots – Multiple LC runs are collected in one
large group. This group can use all spots of all sample carriers.
2-36 D960R3 User’s Manual Probot
Installation and Getting Started
Multiple injections, collect each run in a new group - Multiple LC runs are
collected in the same number of groups. Typically, one group refers to one sample carrier. A group can also use multiple carriers or multiple groups can be collected on one carrier, depending on the needs of the application.
These three options are called ‘collection presets’ and a schematically preview is presented in the wizard (FIGURE 2-38).

Next.
Note: The proper setting of the delay or dead volume is especially important in
the external control mode. In the instant that a peak is detected by the detector, the peak of interest is still in the flow cell and it takes a certain time to reach the Probot needle (the ‘delay’ time, which defined by the tubing volume).

FIGURE 2-43 The Fractionation Application Wizard – Z-Coordinate for Horizontal Movements
2-40 D960R3 User’s Manual Probot
Installation and Getting Started
On default the Probot table moves to its lowest position (0.0 mm) for all horizontal movements. This means, when moving from one spot to the next the table first moves down to its lowest position, and then it moves up upon arrival at the new XY position. This movement may take several seconds.
The ‘spotting time’ is defined as the actual time required to spot and the time to move the table:
tspotting = tmovement + ton spot
To reduce the time to move the table to a minimum, a ‘special Z coordinate for horizontal movements’ can be programmed so that the table will move all the way down. This table height (Z-axis) is used during movements. It is defined as the height above the lowest table position (0.0 mm).
In addition to the Z movement, XY movements can be optimized by choosing an appropriate spotting pattern (e.g. meander vs. saw tooth pattern).
To define the ‘special Z coordinate for horizontal movements’, the table is moved to the desired travel height using the Manual Drive Panel (Section 2.8.5 A):

3.2 Maintenance

Maintenance refers to a variety of activities that should be performed on a routine basis to optimize performance of the system. Many routine maintenance activities can be readily performed by the user.
In some cases (e.g. replacement of critical components), we recommend that a factory trained service engineer should be called to perform the operation. This will ensure optimal long term performance and maximum uptime. LC Packings provides a broad range of service support activities to ensure that the Probot Micro Fraction Collector is functioning in a suitable manner. These activities can be customized to meet the specific needs of the customer. For further information, please contact your local LC Packings office or representative.

Note: The frequency of the various activities described above is a good starting
point. As the user gains experience with the system, it will be found that some activities can be done less frequently and other need to be done more frequently. The frequency is dependent on a number of factors including the nature of the sample and the mobile phase.

3.3 Replacing Major Components

A variety of components on the Probot Micro Fraction Collector can be readily changed by the user as required to ensure that the instrument is maintained in optimal condition. In some circumstances the analyst may want to alter the configuration of the system (e.g. installing the pipetting option, Section 3.3.1).
In most cases, re-assembly of a component is identical to its disassembly, except that the steps are performed in the reverse order. If no comment is made, it should be assumed that the assembly of a component or installation of a component is identical to disassembly or removal, except that the actions are in the reverse order.
WARNING
Warning: Hazardous voltages are present inside the instrument. Disconnect the
instrument from the electrical supplies before removing any panel or cover.
3.3.1 Installing the Pipetting Option
The pipetting option (P/N 161072) allows for pipetting from a source plate (e.g. a well plate) to a destination plate (e.g. MALDI target). It consists of a Teflon tube (45 cm, I.D. 250

3.4 Troubleshooting

Troubleshooting refers to the determination of the cause of a problem. Since the Probot Micro Fraction Collector is typically incorporated into an HPLC system, the first step is to determine if the problem is due to the collector. The Probot should be removed from the system and an injection should be performed. Compare the results from the two runs; if the observed results without the Probot present acceptable data, the problem is most likely due to the Probot Micro Fraction Collector.
Analytical problems also might be caused by external influences, like temperature and/or light sensitive samples. For this reason it is important to be sure the application was running without problems before and nothing has been changed.
TABLE 3-4 Troubleshooting the Probot Micro Fraction Collector
Problem Probable Cause Solution
The table drops during a run or homes itself unexpectedly.
The distance between needle and table increases during a run.
Strange noise from the stepper motors, table not moving. Different volume of droplets or no droplets on the target (e.g. the following pattern is obtained):
Wrong OK
Wrong control parameter.
The Z-stepper motor is missing steps.
TTL signals are generated very shortly after each other.
Wrong control parameter. The Z-stepper motor is
missing steps.
Wrong table alignment.
The motor is losing steps.
Air in the connecting tubing or in the syringe.
Probot needle with the fused silica capillary is too far above the target.
Fused silica capillary not properly installed.
Fused silica capillary/needle is damaged.
Wrong table alignment.
Check the maximum speed and acceleration settings (Section 2.8.7).
Check the timing (Sections B.6 and D.6).
Check the maximum speed and acceleration settings (Section 2.8.7).
Check table alignment (APPENDIX C). Check the maximum speed and acceleration settings (Section 2.8.7). Check the entire flow path for air bubbles (e.g. syringe, tubing, etc.). Adjust the table height (e.g. the fused silica capillary should touch the target during sample deposition when nano flows are applied). Visible part of the fused silica capillary should extend the needle by 0.5 – 1 mm.
Replace capillary/needle.
Check table alignment (APPENDIX C).
The first droplets are different (e.g. too small).
Crystallization of the matrix solution on the needle tip.
Perform a wash and/or a dispense step prior fractionation.

Peak Collection in Conjunction with CHROMELEON® Software

B.1 Overview

This appendix describes how to setup the Probot Micro Fraction Collector for peak collection in conjunction with the CHROMELEON
The peak detection capabilities of CHROMELEON can be used to control event outputs (e.g. event outputs of the UltiMate generated at the beginning of a peak and at the end of the peak. The conditions that CHROMELEON uses to detect peaks can be programmed and adjusted to the needs of the application.
The peak collection function of the Probot Micro Fraction Collector and the
Carrier software involves the TTL inputs (Section 2.4.1 D).
The information provided in this appendix refers to CHROMELEON version 6.5 SP3 and to
Carrier version 2.0.
Micropump) so that a signal is
software.
User’s Manual Probot D960R3 B-1
Appendix B
B.2 Contact Closure Signals for Peak Detection with
CHROMELEON
The following example uses three relay outputs of the UltiMate Micropump. The relay 1 (event output 7) will generate the ‘Peak Start’ signal while relay 2 (event output 8) will generate the ‘Peak End’ signal. The OC1 output (event output 3) is used to generate the ‘START’ signal for the remote start of the software. The pulse length of all signals is 1 second.
The peak start will be generated if the slope of the UV signal exceeds a certain limit (e.g. 0.1 mAU/sec), the peak end signal will be generated if the UV signal is lower than a certain limit (e.g. 1.0 mAU) and
if the slope of the UV signal drops
beyond a certain limit (e.g. - 0.03 mAU/sec).
The following listing shows the programming of these limits, a complete listing of this example is presented in Section B.5.
Trigger peakstart UV_VIS_1.Delta > 0.1, true=2.00 Pump_Relay_1.State = On Pump_Relay_1.Duration = 1.00 EndTrigger
Trigger peakend UV_VIS_1 < 1.0 and UV_VIS_1.Delta > -0.03, true=2.00 Pump_Relay_2.State = On Pump_Relay_2.Duration = 1.00 EndTrigger

The parameters “UV_VIS_1.Delta” and “UV_VIS_1” can be used independently, you can define either or both and they need to be modified according the requirements of your application.

B.3 Setting up µ-Carrier for Peak Collection

The following sections describe how to setup the Carrier (V2.0) software for peak collection. The Probot Micro Fraction Collector is controlled via external contact signals (START, TTL inputs). The detected peaks are collected in collection vessels and the mobile phase in between peaks can either be collected into one waste vessel or into a group of waste vessels.
To setup
Prepare a collection group with the amount of vessels required to collect all

Note: The number of vessels required to collect the peaks and the waste may
differ and depends on the chromatography conditions (e.g. the peak resolution) and the trigger settings.
b) If required, define a park position and a wash position. FIGURE B-3 shows all
groups used for the peak collection task in this example.

B.6 Additional Hints/Troubleshooting

For the proper handling of a fractionation task and to make sure that no peak is lost, it is important to calculate or measure the delay time between the flow cell of the detector (where the peak is detected) and the fractionation needle (where the peak then will be collected).
If two Peak Start (TTL 1) signals are generated immediately after each other, the Probot moves to the next vial.
If two Peak End (TTL 2) signals are generated immediately after each other, the Probot moves the table to the next vial or stays in the waste vial if a waste position is selected.
Some older collection in only one waste vessel; it requires that you define as many waste positions as collect positions (Section B.3 ). To get only one ‘virtual’ waste position with the proper amount of vessels, you can program a very small distance (e.g. only 0.1 mm) between each vessel.
For additional information refer to the Task, Section 5-51), the CHROMELEON on-line help (e.g. tutorial, see trigger) and to the UltiMate User’s Manual.

Table Alignment Instructions

C.1 Overview

This appendix provides information about how to check the alignment of the table of the Probot alignment is important to make certain that the distance of the fused silica needle remains constant at all X and Y positions.
Note: It is recommended that you check the alignment whenever the instrument
has been moved (e.g. after shipping or relocation of the instrument).

C.2 Table Alignment

To check the table alignment (X and Y), the Manual Control Unit (in conjunction with the performing any check or aligning of the table, the Probot instrument must be properly leveled.
C.2.1 Leveling
Before checking the alignment or performing any alignment, check to ensure that the Probot is properly leveled. Use a spirit level if there is any doubt (FIGURE C-
10). If necessary, adjust the four feet until the instrument is leveled properly.

C.2.2 Test Needle and Carrier Setup
Note: The following procedure discusses all steps using the standard needle. If
the µ-Tee is installed, all steps are identical except step a).
A piece of fused silica is used as ‘test needle’. The table is then moved as close as possible to the needle tip. The manual control unit is used to control the table position.
a)
Install a piece of fused silica capillary. Adjust ‘X’ to 1 – 2 mm (0.04 – 0.08
inch).

Control the position of the table by the appropriate buttons (e.g.: press on
the X+ and X- buttons to move the table to the left or right side [X­direction]).
To change from step mode to continuous movement, press the appropriate
e)
button of the manual control unit. To change the length of each step (speed), adjust the ‘Stepwidth’ parameter.
C.2.3 Checking and Aligning of the X-axis and Y-axis
To check/ align the X-axis:
Remove all targets from the table adapter and remove the adapter from the
a)
table.
Lift the table and position the table so that one of the two small grooves
b)
(item 1, FIGURE C-13) is located directly under the needle tip. Adjust the distance between the needle tip and the table to approximately 0.1 mm (0.004 inch, use the camera for positioning, if available).

c) Move the table from one side to the other (X-direction) and check that the
needle is centered above the groove and that the distance to the needle tip remains constant.
Move the table to the front and to the back (Y-direction) and check that the
d)
distance to the needle tip remains constant.
In case the table needs some adjustment, proceed as follows.
C.2.4 Alignment of the X-axis
To adjust the X direction:
Loosen the two screws labeled ‘3’ in FIGURE C-13.
a)
Turn the two screws labeled ‘2’ in FIGURE C-13 clockwise to lift the table on
b)
the left side, turn the screws counterclockwise to lower the table on the left side.
Note: Turn both screws labeled ‘2’ in FIGURE C-13 by the same angle to keep
the Y-adjustment (e.g. to lift the table on the left side by 1mm, turn both screws approximately 30 degrees clockwise).
c) Retighten the screws labeled ‘3’ in FIGURE C-13 and check the X-direction
again.
d)
Repeat step a) – c) if necessary.
C.2.5 Alignment of the Y-axis
To check/adjust the alignment of the Y-axis:
Remove the cover plate to get access to the adjustment screws (FIGURE C-
a)
14).
FIGURE C-14 Removing the Cover Plate of the Y-axis
b) Slightly unscrew the screws labeled ‘4’ – ‘6’ in FIGURE C-15, but do not
loosen screw 3.
