SIFT-MS A New air quality monitoring technique for real-time detection of volatile compounds


Air pollution has been described by the World Health Organization (WHO) as the largest single environmental health risk and attributes eight million deaths annually as a result of exposure to air pollution. Air is, however, a dynamic matrix and is complex at trace levels. Conventional analytical techniques (such as those based on gas chromatography) lack the time resolution and responsiveness required to provide timely answers so that the root cause of air quality perturbations can be rapidly identified and addressed. Selected ion flow tube mass spectrometry (SIFT-MS) is a direct mass spectrometric technology for continuous and selective robust analysis of ambient air for trace volatile organic compounds and inorganic pollutants. This presentation will introduce the SIFT-MS technique and provide example data from case studies in New Zealand and East Asia (China and Vietnam).
