8.3. Multipoint Calibration Procedure
The procedure for calibration of chemiluminescence NO
x
analyzers by GPT is specified in the
Federal Register.
1
This section applies the general procedure to the specific case of the
M200E.
Calibration must be performed with a calibrator that meets all conditions specified in the
Q.A. Handbook. Flow settings used in the GPT calibration for NO
2
must be determined as
illustrated in Section 3.6, this manual.
The user should be sure that all flow meters are calibrated under the conditions of use
against a reliable standard. All volumetric flow rates should be corrected to 25
o
C (78
o
F)
and 760 mm (29.92 in.) Hg. Calibrations of flow meters are discussed in the QA Handbook,
Vol. II, Part 1, Appendix 12
6
.
Gas Phase Titration (GPT) requires the use of the NO channel of the analyzer to determine
the amount of NO
2
generated by titration. Therefore it is necessary to calibrate and
determine the linearity of the NO channel before proceeding with the NO
2
calibration. It is
also necessary to calibrate the NO
x
channel. This can be done simultaneously with the NO
calibration. During the calibration the M200E should be operating in its normal sampling
mode, and the test atmosphere should pass through all filters, scrubbers, conditioners, and
other components used during normal ambient sampling and as much of the ambient air
inlet system as is practicable. All operational adjustments to the M200E should be
completed prior to the calibration. The following software features must be set into the
desired state before calibration.
•
Automatic converter efficiency compensation. See Section 7.1.7 of this manual.
•
Independent reporting range selection. See Section 6.5.4 of this manual.
•
Automatic temperature/pressure compensation. See Section 6.5.
•
Alternate units, make sure ppb units are selected for EPA monitoring. See
•
Auto ranging reporting range option. See Section 6.5.5.
