Teledyne M201E manual Calibration Procedure

2.0 CALIBRATION PROCEDURE

This section begins with a high-level overview of the calibration procedure for the M201E analyzer. Details are provided starting in Section 2.1:

∙First, take the time to read the M200E manual to familiarize yourself with the Chemiluminescence process. It is important to remember that the analyzer is merely measuring different levels of nitric oxide sample gas on three separate channels (TNx, NOx, NO). The ammonia and nitrogen dioxide concentrations are then calculated using this information.

∙Assemble the M201E analyzer according to the pneumatic configurations outlined in Figure 1-1. Remember: DO NOT pressurize the sample, span or zero ports (Zero/SPAN valves are optional) during calibration. Allow the analyzer to pull the gas through the system using the vacuum pump.

CAUTION!

If the presence of ozone is detected at any time, call Teledyne API Customer Service as soon as possible:

800-324-5190 or email: api-customerservice@teledyne.com

∙Next, zero the analyzer using an approved zero air source, such as, bottled zero air, nitrogen or zero air generated by a Teledyne-API M701 zero air source. This sets the zero offset for the three individual channels (TNx_OFFS, NOx_OFFS, NO_OFFS). Confirm that all displayed concentrations read zero.

∙Span the analyzer using bottled nitric oxide gas diluted to a level set to 80% of the expected sample range, preferably using a M702 Calibrator. This sets the slope for the three individual channels (TNx_SLOPE, NOx_SLOPE, NO_SLOPE). Confirm that displayed concentrations TNx , NOx and NO display the correct span concentration.

∙If you haven’t done so recently, conduct a GPT (gas phase titration) and confirm the molybdenum is functioning accordingly. Section 8.3.3 of the M200E manual outlines the GPT procedure. Section 7.0 of this manual consists of a service note for checking the molybdenum converter. There should be no reason to adjust the molybdenum efficiency factor on a new analyzer. If a diluted bottled of nitrogen dioxide gas is used to determine the molybdenum efficiency, allow enough time for the span value to stabilize. Nitrogen dioxide exhibits similar hold up issues as ammonia gas. Therefore, it may take a number of hours before the NOx reading stabilizes.

∙Span the analyzer using bottled ammonia gas diluted to a level set to 80% of the expected sample range, preferably using a M702 Calibrator. Note:
