Startup and Operation
Each Orion 2295 Phosphate Analyzer gets thoroughly wet-tested and calibrated at the factory,
so the system is ready to begin analyzing sample streams. The results of this activity are
recorded in a Quality Control Report shipped to you with the analyzer.
Since the elapsed time between factory calibration and your startup process is unpredictable, it
is important that you calibrate the analyzer again before you place it in service for the first time.
Please refer to section
Calibration
for additional instructions on calibrating the analyzer. The
reported result of a calibration is a number that the analyzer uses to determine the sample
concentration. The particular value of this number is not important, but it should be within ± 5%
of the corresponding value in the Quality Control Report. If so, you can be confident that all
subsystems of your analyzer are working properly.
Before proceeding, please make sure of the following:
The reagent bottle is full and properly connected. Reagent bottle is the reagent used in the
phosphate analysis.
The 10 ppm phosphate
calibration standard (1 L bottle) is full with the standard and
properly connected.
The drain and sample lines are connected. Verify the sample is flowing into the sample
chamber located at the bottom right side of the fluidics enclosure.
The lines are primed and there are no trapped air bubbles in any of the lines.
