OPERATING INSTRUCTIONS M400E Ozone Analyzer Operator’s Manual
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. Ozone audit devices must be referenced to a primary UV
photometer or one of the Standard Reference Photometers maintained by NIST and the US EPA.
10.1.2. 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:
 Equivalent Method photometric O
3
analyzer, such as the T-API Model 400E
 Strip chart recorder and/or data logging system
 Sampling lines
 Sampling manifold
 UV (ultraviolet) photometric calibration system
 Certified calibration transfer standards
 Zero-air source
 Ozone generation device ("calibrator")
 Spare parts and expendable supplies
 Record forms
 Independent audit system
When purchasing these materials, a logbook 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. Chapter 12 of this manual describes the parts that require periodic
repla
cement and the frequency of replacement. Appendix B contains a list of spare parts and kits of
expendables supplies.
10.1.3. 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 generator.
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. We Recommend using a Gas Dilution Calibrator with a built in O
3
generator, such as a T-
API Model 700E, as a source for O
3
Span Gas.
In ALL cases, the instrument(s) supplying the zero air and Span calibration gasses used must themselves be
calibrated and that calibration must be traceable to an EPA/NIST primary standard.
