7.6.7 Calibration Frequency

To ensure accurate measurements of the NO, NOx, and NO2 concentrations, calibrate the analyzer at the time of installation, and re-calibrate it:

1.No later than three months after the most recent calibration or performance audit which indicated analyzer calibration to be acceptable.

2.An interruption of more than a few days in analyzer operation.

3.Any repairs which might affect its calibration.

4.Physical relocation of the analyzer.

5.Any other indication (including excessive zero or span drift) of possible significant inaccuracy of the analyzer.

Following any of the activities listed above, the zero and span should be checked to determine if a calibration is necessary. If the analyzer zero and span drifts exceed the calibration limits in Table 9-1 of Section 2.0.9, Subsection 9.1.3 (Q.A. Handbook), a calibration should be performed.

7.6.8 Other Quality Assurance Procedures

Precision is determined by a one-point check at least once every two weeks. Accuracy is determined by a three-point audit once each quarter.

Essential to quality assurance are scheduled checks for verifying the operational status of the monitoring system. The operator should visit the site at least once each week. Every two weeks a Level 1 zero and span check must be made on the analyzer. Level 2 zero and span checks should be conducted at a frequency desired by the user. Definitions of these terms are given in

Table 7-16.

In addition, an independent precision check between 0.08 and 0.10 ppm must be carried out at least once every two weeks. Table 7-16 summarizes the quality assurance activities for routine operations. A discussion of each activity appears in the following sections.

To provide for documentation and accountability of activities, a checklist should be compiled and then filled out by the field operator as each activity is completed.
