Advanced Pollution Instruments (API) Model 400 Ultraviolet Absorption Ozone analyzer: The State of Vermont APCD operates two continuous ozone monitoring sites within the state. The instrument samples local ambient air quality 24 hours a day, 365 days a year. Averaging intervals of 1, 5, 60, 480 minutes are automatically logged with the data acquisition systems. The unit is setup and operated to monitor ambient ozone concentrations up to 500 parts per billion. The one hour ozone and running eight hour averages from the two monitoring sites are compiled and presented on a hourly basis on this web site. Reference/Equivalent Method Designation: The Model 400 is designated by EPA as a automated Equivalent Method (EQOA-0992-087) for the measurement of ambient concentrations of nitric oxide. The Model 400 must be and is set up and operated as per the reference designation. Principle Utilized: The instrumental operation utilizes the principle of "Ultraviolet Absorption" that is based on the fact that ozone molecules absorb ultraviolet energy at a known wave length of 254nm. The UV light available for detection is proportional to the amount of ozone in the sample chamber.
