Teledyne 9110T instruction manual Calibration EQUIPMENT, SUPPLIES, and Expendables

Model 9110T NOx Analyzer EPA Protocol Calibration

Calibrations should be carried out at the field monitoring site. The analyzer should be in operation for at least several hours (preferably overnight) before calibration so that it is fully warmed up and its operation has stabilized. During the calibration, the 9110T:

∙Should be in the CAL mode,

∙The test atmosphere should be supplied through all components used during normal ambient sampling and through as much of the ambient air inlet system as is practicable.

∙If the instrument will be used on more than one range, it should be calibrated separately on each applicable range.

∙Details of documentation, forms and procedures should be maintained with each analyzer and also in a central backup file as described in Section 12 of the Quality Assurance Handbook.

∙Personnel, equipment and reference materials used in conducting audits must be independent from those normally used in calibrations and operations.

10.2.CALIBRATION EQUIPMENT, SUPPLIES, AND EXPENDABLES

The measurement of NOx, NO and NO2 in ambient air requires a certain amount of basic sampling equipment and supplemental supplies. These include, but are not limited to, the following:

When purchasing these materials, a logbook should be maintained as a reference for future procurement needs and as a basis for future fiscal planning.

10.2.1. SPARE PARTS AND EXPENDABLE SUPPLIES

In addition to the basic equipment described in the Q.A. Handbook, it is necessary to maintain an inventory of spare parts and expendable supplies. Section 11 describes the parts that require periodic replacement and the frequency of replacement. Appendix B contains a list of spare parts and kits of expendables supplies.
