In this article, the results of a DIMS air monitoring campaign in Auckland, New Zealand, are described. Real-time SIFT–MS measurements were obtained at three sites over a period of several weeks. At each site, SIFT–MS provided effective on-site analysis to sub-ppbV levels with better than 1-min time resolution.
This application note describes the determination of method detection limits (MDLs) for the newly regulated HON (Hazardous Organic NESHAP) compounds, which validate SIFT-MS as an effective solution for measuring these toxic VOCs and other environmental pollutants in ambient air, whether at the fence line or in a mobile setting.
This study demonstrates high-throughput analysis of BTEX compounds from several matrices (air, water and soil). Detection limits in the single-digit part-per-billion concentration range (by volume) are readily achievable within seconds using SIFT-MS, because sample analysis is achieved without chromatography, pre-concentration, or drying. We also present a calibration approach that enables speciation of ethylbenzene from the xylenes in real-time.
This application note summarizes key SIFT-MS results presented in a peer reviewed article entitled “Unreported VOC Emissions from Road Transport Including from Electric Vehicles.” Learn how the Wolfson Atmospheric Chemistry Laboratory at the University of York used SIFT-MS for VOC analysis in its platform to experimentally verify that motor vehicle screen wash is a significant unreported source of VOC emissions (especially for ethanol and methanol).
This brochure SyftEnviro environmental monitoring software which is a comprehensive solution for visualizing data from mobile monitoring campaigns. It provides a user-friendly interface for collecting, mapping, and analyzing data taken by environmental monitoring technicians while investigating environmental emissions. SyftEnviro provides the tools to identify pollution sources and take immediate action.
This publication reviews VOC pollutant monitoring applications of SIFT-MS in South Korea. SIFT-MS has been applied to emission source characterization, fenceline monitoring, ambient monitoring, pollution mapping, and incident response (including the use of drone-based sampling) for hazardous air pollutants (HAPs), odor nuisance species, and compounds that have high ozone formation potential (OFP) and/or contribute to secondary aerosol (SOA) formation.
HPLC coupled with negative ESI-MS provides a reliable method with unique capabilities for separation and identification of (therapeutic) oligonucleotides.
