Rationale

Recent technological advances in air monitoring instrumentation (e.g. proton transfer reaction mass spectrometry, PTR-MS) have enabled the measurement of chemicals at orders of magnitude higher time and lower concentration resolutions compared to older instrumentation. However, quantification using this new equipment is challenged in part because of a paucity of standards that define operational best practices and data quality control procedures. Increasingly, standard test methods are recommending PTR-MS instruments for measurement of volatile organic compounds in indoor environments (e.g., ASHRAE 145.2 and 145.4, ASTM D6670, ISO 16000-3). Measurement and quantification of volatile organic compounds indoors is currently performed in a variety of applications including product emissions testing, chamber and in-duct testing and safety verification of air cleaning technologies, and wildfire smoke damage testing—to name a few. Additionally, the private consumer market demands for disaster response and smoke damage measurements are growing.
