General Information

2.2 General product information

The system unit manages five sample processing modules or channels, configured for performing flow injection analysis with photometric detection. The number of channels can be expanded to a maximum of eight by adding a second core. Alternate configurations, such as potentiometric and amperometric detection methods are described in the analytical method where they are required. For complete information on the software, refer to the QuikChem FIA Omnion® Software Manual or the on-line help system in the software.

The QuikChem® 8500 Series 2 analyzer is modular in design (Figure 3) and consists of the following modules:

•Dilutor (optional)—The PDS200 uses positive displacement to draw diluent water to mix with non-flammable samples for analysis. Refer to section 3.4 on page 25.

•Sampler—The QC8500 Analyzer works with either the ASX-400 or ASX-500 series autosamplers. Refer to section 3.3 on page 21.

•Reagent Pump (12 or 16 cartridges)—The multichannel peristaltic pump is used to pump reagents into the manifold. It also aspirates sample aliquots from the sampler to the valve. These portions are then loaded into the sample loop and swept into the manifold by the carrier stream to mix with the reagents.

•QuikChem FIA System Unit—The System Unit consists of the core unit and the sample processing modules (SPM). The core unit distributes power, light and electronic signals to and from each SPM. A sample processing module, also known as a channel, typically consists of an injection valve, a manifold, a photometric detector and a heating module (optional). A System Unit can have up to five channels that run simultaneously. A single computer can control two System Units in order to run up to eight channels at once. A chemical reaction module or manifold is installed on a channel for the quantitative analysis of an analyte. There are more than 450 QuikChem methods available for determining over 40 analytes; many of them in several matrices.

•Computer

•Printer (optional)

Note: If any items are missing or damaged, contact the manufacturer or sales representative immediately. Ship the components returned for service in the original packaging material to protect against damage during transportation.

Note: The Ion Chromatography option is available with this instrument. Refer to the QuikChem Ion Chromatography User Manual for instructions.

3.3.2 Unpack the ASX sampler

Note: If any of these items are missing or damaged, contact the manufacturer or sales representative immediately. Ship the instruments returned for service in the original packaging material to protect against damage during transportation.

ASX samplers are shipped with:

•Sample tray(s), assembled and installed

•Probe tube in styrofoam container

•Tubing kit with waste line, sample line and probe

To unpack the sampler:

1.Remove the sampler from the shipping carton and protective plastic and place on the laboratory bench.

2.Remove the probe arm from the styrofoam container and lay carefully on top of the sample racks.

3.Open the tubing kit and identify the components required for fluidic connections.

Installation

3.3.3 Sampler setup

To connect the sampler:

1.Connect the power cord to the power strip. Leave the power strip switched off.

2.Connect the supplied RS232C cable to the 9-pin connector (COM1) on the back of the sampler.

3.Connect the other end of the RS232C cable to COM1 on the computer.

3.3.4Mount Z-drive

Except for the Z-drive, the sampler is assembled at the factory.

To mount the Z-drive on the sampler arm:

1.Remove thumbscrews and bushings from the drive block located on the sampler arm (Figure 20 on page 23).

2.Attach the x-axis slider block on the arm tube.

3.Secure the slider block finger-tight with the 12-mm thumbscrews (installed from the top).

3.3.5Probe installation

To install the probe:

1.Loosen the probe knob on the probe tube slider and remove the piece of tubing installed for shipping. Lift the probe tube slider until it stops.

Note: The tan knob will come off without the tubing or probe to hold it in place.

2.The guide slider will move to the upper position with the probe tube slider. Use the wheel in the back of the sampler to lower both sliders until the guide slider is about 1 mm from the top. Make sure that the two sliders are in contact.

Note: Always move the sliders using the wheel at the back of the sampler to avoid crimping the PEEK tubing.

3.Install the sample probe through both sliders, the probe knob and the opening on the probe guide plate. Keep the sliders about 1 mm from the top. Adjust the probe so the tip is 3 to 6 mm below the guide plate. To secure the probe, tighten the probe knob on the probe tube slider.

4.Move the sampler arm to the rinse station (extreme left position in the standards rack). Verify if the probe tip clears the top of the rinse station when the sampler is in the home position.

3.3.6 Fluidic connections

3.3.6.1 Connect the rinse station

Rinse solution is pumped into the bottom of the rinse station and drains to a waste container through drain tubing attached at the top of the station (Figure 21).

To connect the rinse station:

1.Connect the rinse-in end of the wash line assembly to the inlet fitting (bottom).

2.Install the pump tube with the purple pump tube tabs on the pump. Refer to section 3.2.3 on page 18.

Note: The outlet of the tube on the right side of the pump attaches to the inlet of the wash bath (Figure 21, item 1).

Important Note: Do not lock down the right side of the pump cartridge until ready to perform the test.

3.Drop the other end of the wash line into the rinse solution.

4.Connect one end of the Tygon drain tubing to the drain fitting (top). Drop the other end into a waste container.
