| Abstract |
In February, 1979, EPA revised certain parts of the ambient air pollution monitoring regulations (40 CFR Part 50, Appendix D) to specify a new procedure for calibration of ambient ozone analyzers. The new procedure is based on ultraviolet (UV) absorption photometry, and specifies in detail the UV photometer, other apparatus, and the procedure necessary for establishing quasi-primary ozone concentration standards derived from the known absorption coefficient of ozone at 254 nm. This Technical Assistance Document is intended to provide information and assistance to State monitoring agencies and other organizations which must use the new procedure to calibrate ambient ozone analyzers. The first section of the document is a discussion of absorption photometry, with emphasis on the transmittance measurement and measurement errors. Section 2 provides step-by-step explanatory information and advice keyed to each paragraph of the procedure. Section 3 discusses UV photometers specifically, their design and operational characteristics, and several commercially available models. |
