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.
