It should be noted that there are still unresolved discrepancies in oxidant data owing to differences in primary standards. lodometric calibration techniques for ozone monitors were compared by an ad hoc committee appointed by the California Air Resources Board (carb). The committee set out to find an accurate method for measuring ozone, to relate the recommended method to earlier data, and to recommend... [Pg.126]

The airborne monitoring program concentrated on the measurement of ozone to provide supplementary air quality data for various altitudes over the fixed sites. The airborne measurements were conducted in a C-45 aircraft that carried a solid-face chemiluminescent ozone monitor. The ozone meter was cycled every 2 min to provide calibration, purge, measurement, and purge at equal intervals. The sparseness of the airborne data precluded... [Pg.149]

Most currently used oxidant and ozone monitors need to be calibrated with a predetermined concentration of ozone in air. Regardless of the principle used to measure ambient ozone or oxidant concentrations, the primary reference standard for calibrating each monitoring device or system should be identical everywhere. This requirement remains to be achieved in practice. Up to June 1975, at least seven calibration procedures were practiced in the United States. These are listed in Table 6-5... [Pg.249]

For reliable calibrations, it was necessary to develop a stable and reproducible ozone source that could produce ozone in air at concentrations smaller than parts per million. After this was accomplished, several different versions were engineered they are now available commercially from vendors of most ozone-monitoring instruments. The factors affecting the production and survival of oxygen species other than ozone are discussed in Chapter 12. Care must be taken to prevent these species from creating interference when ozone is generated for instrument calibration. [Pg.251]

Advanced electro-optical methods (e.g., laser resonance absorption) capable of measuring average concentrations over long distances still requite extensive research and field testing to demonstrate their practical application to ozone monitoring. Because electro-optical methods have not yet been widely used, they are not discussed further here. [Pg.262]

Note For safety reasons ozone should always be used with an ambient air ozone monitor (measuring ranges 0-1 ppm) with a safety shut down procedure. [Pg.7]

Ambient air ozone monitor. Is it necessary to check the ambient air ozone concentration in the lab Yes, it is highly recommended to control the lab environment and connect the monitor to the ozone generator so that the ozone production will be shut off in case of leakage in the system B 2.5...
