7.6.10.2 Precision Check

A periodic check is used to assess the data for precision. A one-point precision check must be carried out at least once every 2 weeks on each analyzer at an NO2 concentration between 0.08 and 0.10 ppm. The analyzer must be operated in its normal sampling mode, and the precision test gas must pass through all filters, scrubbers, conditioners, and other components used during normal ambient sampling. The standards from which precision check test concentrations are obtained must be traceable to NIST-SRM. Those standards used for calibration or auditing may be used.

7.6.10.3 Precision Check Procedure

1.Connect the analyzer to a precision gas that has an NO2 concentration between 0.08 and 0.10 ppm. NO2 precision gas may be generated by either GPT or a NO2 permeation tube. If a precision check is made in conjunction with a zero/span check, it must be made prior to any zero or span adjustments.

2.Allow the analyzer to sample the precision gas until a stable trace is obtained.

3.Record this value. NO and NOx precision checks should also be made if those data are being reported. Information from the check procedure is used to assess the precision of the monitoring data; see Section 2.0.8 (Q.A. Handbook) for procedures for calculating and reporting precision.

7.6.11 Recommended Standards for Establishing Traceability

To assure data of desired quality, two considerations are essential: (1) the measurement process must be in statistical control at the time of the measurement and (2) the systematic errors, when combined with the random variation in the measurement process, must result in a suitably small uncertainty.

Evidence of good quality data includes documentation of the quality control checks and the independent audits of the measurement process by recording data on specific forms or on a quality control chart and by using materials, instruments, and measurement procedures that can be traced to appropriate standards of reference. To establish traceability, data must be obtained routinely by repeated measurements of standard reference samples (primary, secondary, and/or working standards). More specifically, working calibration standards must be traceable to standards of higher accuracy, such as those listed below in Table 7-17.
