Orion 2210AM Ammonia Analyzer
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.

The calibration standard and corresponding part number,
required for this application is determined in the following
table based on the concentration range of interest. Each
calibration cycle consumes approximately 25 mL. Each bottle
contains enough standard solution for approximately
20 calibrations.

Reagents Required
Reagent Kit: 2210REC contains both reagents. Two kits exist
2210RECLR (low range) and 2210RECHR (High range).
The analyzer requires two reagents, one cleaner 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 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.
