Assessing phosphate concentration may be necessary to ensure that no differences are observed with modulating concentration. This ensures proper sample recovery and demonstrates robustness of the method. In this application note, we review SEC chromatographic performance for trastuzumab and NIST mAb modulating concentration of potassium phosphate.
Real-Time Measurement of EPA Regulated HON Compounds and Environmental Pollutants Using SIFT-MS
September 6th 2024This 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.
High-Throughput Analysis of Volatile Compounds in Air, Water, and Soil Using SIFT-MS (Sept 2024)
September 6th 2024This 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.
Real-Time Roadside Monitoring of Unreported VOC Emissions from Road Transport by SIFT-MS (Sept 2024)
September 6th 2024This 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).
Adoption of SIFT-MS for VOC Pollution Monitoring in South Korea (Sept 2024)
September 6th 2024This 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.
