Standard Operating Procedure for Zero-Air Generators

Continuous ambient air analyzers require multipoint calibrations on a routine monthly basis and after major maintenance is completed. This procedure describes the role of Zero-Air Generators in supplying pure, dry air as a source of calibration standard. This Standard Operating Procedure details two alternate Zero-Air sources: Perma Pure Inc.’s Zero-Air Generator (ZAG), and Advanced Pollution Instrumentation’s (API) Zero-Air Module. This method adheres to the requirements of the current Air Monitoring Directive (AMD) drafted by Alberta Environment in 1989. In some cases the limits and specifications exceed the requirements of the current AMD and subsequent amendments. It should be considered that the current and any future amendments or drafts of the AMD will be used as the benchmark for requirements and criteria for ambient air monitoring practices conducted in the Province of Alberta. Information used to write this procedure was also taken from sources identified in the reference section.
