Calibration Equipment, Supplies, and Expendables
The measurement of O
3
in ambient air requires a certain amount of basic sampling
equipment and supplemental supplies. These include, but are not limited to, the
following:
1. Equivalent Method UV Photometric O
3
analyzer, such as the T-API Model 400E
2. Strip chart recorder and/or data logging system
3. Sampling lines
4. Sampling manifold
5. UV (ultraviolet) photometric calibration system
6. Certified calibration transfer standards
7. Zero-air source
8. Ozone generation device ("calibrator")
9. Spare parts and expendable supplies
10.Record forms
11.Independent audit system
When purchasing these materials, a log book should be maintained as a reference
for future procurement needs and as a basis for future fiscal planning.
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 9 of this
manual 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.
8.1.3.
Calibration Gas and Zero Air Sources
Production of Zero Air
Devices that condition ambient air by drying and removal of pollutants are available
on the commercial market such as the API Model 701 Zero Air Module.
Production of Span Gas
Because of the instability of O
3
, the certification of O
3
concentrations as Standard
Reference Materials is impractical, if not impossible. Therefore, when O
3
concentration standards are required, they must be generated and certified locally.
