Expression of performance of gas analyzers. Tuneable semiconductor laser gas analyzers | Status: Current, Under review

1 Scope This part of IEC 61207 applies to all aspects of analyzers utilizing TSLAS for the concentration measurement of one or more gas components in a gaseous mixture or vapour. It applies to analyzers utilizing tuneable semiconductor lasers as sources and utilizing absorption spectroscopy, such as direct absorption, FMS, WMS, multi-pass absorption spectroscopy, CRDS, ICOS, PAS and CEAS techniques, etc. It applies both to in situ or extractive type analyzers. This standard includes the following, it

• — specifies the terms and definitions related to the functional performance of gas analyzers, utilizing tuneable semiconductor laser gas absorption spectroscopy, for the continuous measurement of gas or vapour concentration in a source gas,
• — unifies methods used in making and verifying statements on the functional performance of this type of analyzers,
• — specifies the type of tests to be performed to determine the functional performance and how to carry out these tests,
• — provides basic documents to support the application of the standards of quality assurance with in ISO 9001
