4 | Introduction Orion 2210AM Ammonia Analyzer
Introduction
The Thermo Scientific Orion 2200 series analyzers are
compact wet-chemistry analysis systems, designed for the
continuous on-line analysis of water in several applications
across many industries.
The Orion 2210AM Ammonia Analyzer uses the colorimetric
detection method that relies on specific reagents that are
added to the sample to produce a reacted color compound.
The intensity of the color determines the concentration in
reference to a known reacted standard. The colored
compound absorbs energy at a specific wavelength in
accordance with the Beer-Lambert Law.
The instrument uses Light Emitting Diodes (LEDs) that emit
light at a narrow bandwidth selected for the specific
application.

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
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.
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.
