Regulators are imposing tighter and more comprehensive emissions requirements for controlling airborne pollutants. Environmental emissions monitoring has traditionally been performed through off-line techniques which lack the speed and resolution to provide timely data on these complex matrices. Online monitoring is an important technique for enabling the rapid identification and source of these emissions.

Selected ion flow tube mass spectrometry (SIFT-MS) is a direct mass spectrometric technology that can speciate and quantify volatile organic compounds (VOCs) and inorganic gases simultaneously and continuously in real-time. SIFT-MS is used by both governmental agencies and industry to monitor emissions in mobile, fenceline, and ambient air settings.

This publication showcases recent advancements to SIFT-MS and their application to environmental protection in South Korea.

This application note describes a platform developed by the Wolfson Atmospheric Chemistry Laboratory at the University of York for monitoring VOC emissions from automobiles including electric vehicles.

This article details an air monitoring campaign in New Zealand where measurements were taken at three different sites over several weeks.

This application note shows how SIFT-MS can be used to detect and identify environmental pollutants at industrial site boundaries before they reach surrounding communities through continuous fenceline monitoring.
