5.Verify that the residence time (tR) in the reaction chamber is <2 min using Equation 7-5:

 

180 cm3

tR =

282 cm3 / min+ 29.5 cm3 / min = 0.58 min

6. Verify the dynamic parameter specification (PR) of the calibrator reaction chamber using Equation 7-6:

 

29.4 cm3 / min

 

180 cm3

PR = 50.5 ppm ×

 

×

 

= 2.75 ppm

282 cm3 / min+ 29.4 cm3 / min

282 cm3 / min+ 29.4 cm3 / min

7.Calculate the diluent air flow (FD) required at the mixing chamber, using Equation 7-7:

FD = 3300 cm3/min - 282 cm3/min –29.4 cm3/min = 2988.6 cm3/min

7.6.5 Dynamic Multipoint Calibration Procedure

The procedure for calibration of chemiluminescent NOx analyzers by GPT is specified in the Federal Register.1 This section applies the general procedure to the specific case of the M200AU.

Calibration must be performed with a calibrator that meets all conditions specified in Subsection

2.3.2(Q.A. Handbook). Flow settings used in the GPT calibration for NO2 must be determined as illustrated in Section 7.6.4, 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 25oC (78oF) and 760 mm (29.92 in.) Hg. Calibrations of flow meters are discussed in TAD.2

Gas Phase Titration (GPT) requires the use of the NO channel of the analyzer to determine the amount of NO2 generated by titration. Therefore it is necessary to calibrate and determine the linearity of the NO channel before proceeding with the NO2 calibration. It is also necessary to calibrate the NOx channel. This can be done simultaneously with the NO calibration. During the calibration the M200AU 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 M200AU should be completed prior to the calibration. The following software features must be set into the desired state before calibration.
