DANGER
Handling chemical samples, standards, and reagents can be
dangerous .
Review the necessary Material Safety Data Sheets and become familiar
with all safety procedures before handling any chemicals .
CAUTION
REAGENT BOTTLES MUST BE KEPT TIGHTLY CLOSED.
Observe all health and safety procedures for handling chemicals. Wash any
spillage with Distilled water.
Allow enclosure to vent any trapped fumes before servicing.
Air purge of enclosure is recommended .
EMPTY ALL REAGENTS BEFORE SHUTTING UNIT DOWN.
Analysis Reaction Principle
The colorimetric method is based on the reaction of reagents with the sample to produce a
color. This color is measured and compared to a standard color, which proportionally defines its
concentration.
The color compound, which is the reacted mixture of the sample with the reagents, absorbs
energy at a specific wavelength in accordance to Beer-Lambert Law.
Fluids Storage
Store all reagents and standards in a dark place at room temperature.
Calibration Standard
Standard part # 223020, the calibration standard required for this application is a 200 ppb
solution. Each calibration cycle consumes approximately 50 mL. Each bottle contains enough
standard solution for approximately 10 calibrations.
Reagents Required
Reagent Kit: 2230RE contains all 3 reagents.
The analyzer requires three reagents and one standard solution. All bottles are housed in the
fluidics enclosure compartment.
For proper operation: Ensure that the reagents are correctly installed, the analyzer tubing is
correctly routed in the pumps and pinch valves, and that the analyzer drain tube is connected to
an atmospheric drain. All of the reagents and standard vent tubes need to exhaust to the
outside of the enclosure, to minimize the trapping of any vapors inside the enclosure.
