7.6EPA Protocol Calibration

If the M200AU is to be used for EPA compliance monitoring, it must be calibrated in accordance with the instructions in this section.

In order to insure that high quality, accurate measurements are obtained at all times, the M200AU must be calibrated prior to use. A quality assurance program centered on this aspect and including attention to the built-in warning features of the M200AU, periodic inspection, regular zero/span checks and routine maintenance is paramount to achieving this.

In order to have a better understanding of the factors involved in assuring continuous and reliable information from the M200AU, it is strongly recommended that Publication No. PB 273- 518 Quality Assurance Handbook for Air Pollution Measurement Systems (abbreviated, Q.A. Handbook) be purchased from the NTIS (phone 703-487-4650). Special attention should be paid to Section 2.3 which deals with chemiluminescent based NO2 analyzers and upon which most of this section is based. Specific regulations regarding the use and operation of ambient oxides of nitrogen analyzers can be found in 40 CFR 50 and 40 CFR 58. Both publications are available from the U.S. Government Printing Office (phone 202-783-3238).

7.6.1 Calibration of Equipment

In general, calibration is the process of adjusting the gain and offset of the M200AU against some recognized standard. The reliability and usefulness of all data derived from any analyzer depends primarily upon its state of calibration. In this section the term dynamic calibration is used to express a multipoint check against known standards and involves introducing gas samples of known concentration into the instrument in order to adjust the instrument to a predetermined sensitivity and to produce a calibration relationship. This relationship is derived from the instrumental response to successive samples of different known concentrations. As a minimum, three reference points and a zero point are recommended to define this relationship. The true values of the calibration gas must be traceable to NIST-SRM's (Section 2.0.7, Q.A. Handbook).
