Internal tasks which are performed on a routine basis to control the accuracy and precision of a measurement process. Calibrations Zero and Span Checks Blanks Duplicates Quality Control

External tasks which are performed on an occasional basis to assess the capability and performance of a measurement process. Performance audits System audits Interlaboratory comparisons Quality Assessment

A quantitative comparison of an air monitoring site’s analyzers and/or samplers with a device of known accuracy. Performance audits may also involve a laboratory’s ability to identify specific compounds. Gas Analyzer Audits Flow Audits MET Audits Laboratory Siting Performance Audits
