During the addition of reagent, the stirrer is on and the info
field (if enabled) shows the reagent pumping progress, with
a bar and the volume pumped. After adding the reagent, the
countdown of stir time is also shown along with the
absorbance of the sample mixture.
If the pump is not assigned to a reagent, it
will abort the measurement and
NOTE:
the info field will flash with the error
message: "PUMP IS NOT ASSIGNED".
Collect Data
In collect data, the final reading is recorded and the final
absorbance is displayed at the end of the cycle.
The stability of the recorded reading depends on the specified
stability criteria. You have the choice of editing the stability
criteria. To do this from the MAIN MENU follow the sequence:
➔ ➔
MENU SETUP ANALYSIS PARAMETERS
➔
STABILITY CRITERIA
Now the concentration is calculated (as follows) and the
current concentration is updated.
Concentration = (Slope x Absorbance) + Intercept
(Where slope and intercept are from the CURRENT calibrated
values of the instrument for measurement.)
If unstable and doesn't meet the stability
criteria, the info field will flash with
NOTE:
the warning message "COLLECTING
DATA, UNSTABLE SIGNAL".
Post Wash
The programmable POST WASH is to wash the reaction cell
after the measurement and evacuate any residue of the
reaction mixed solution. This event is optional and can be
disabled, or the reaction cell can be washed with selectable
sources with editable volumes and stir times, with up to five
programmable steps. To perform post wash after
measurement, select ANALYSIS PARAMETERS for the POST
WASH EVENT.
To set the post wash parameters from the MAIN MENU follow

Measurement Data
The Orion 2210AM Ammonia Analyzer product stores
measurement and calibration results for up to 365 days. The
data for each sample analysis cycle or calibration may be
retrieved under REVIEW RESULTS menu screen with the
corresponding time stamp and other related operating
parameters.
Sample analysis data stores the date, time, concentration,
units, temperature, wavelength and status (Good or Fault)
along with the faults for each measurement cycle.
Calibration data stores date, time, standard concentration,
slope, intercept, temperature, wavelength and status.
The stored results are displayed with respect to the selectable
period of time such as: Last 12 Hours, Last 1 Day, Last 2
Days, Last 3 Days, Last 1 week, Last 2 weeks, Last 3 weeks,
Last 4 weeks, All, which is selected as DATA RANGE. To
display the measurement results from the main menu follow
the sequence:

NOTE:
Printing Results
The stored measurement results can be printed on to the
Hyper Terminal (minicom in Linux) through the RS-232 port
within the selected data range. The selected data range is
applicable to displaying, printing and plotting of measurement
results.

REVIEW ANALYSIS
Validation results are ONLY reported on
the display and the RS-232 at the time of
running the validation. Validation cycles
are not stored and are not reported on the
analog outputs.
