High-Throughput Analysis of Volatiles in Air, Polymers, Water and Soil, Using Direct MS

Overview

Sample throughput is often a critical bottleneck for analysis of volatiles in the contract testing or research laboratory. Selected ion flow tube mass spectrometry (SIFT-MS) is a form of direct mass spectrometry that provides real-time detection of volatile organic compounds and many inorganic gases to sub-part-per-billion concentrations (by volume; ppbv) without preconcentration, derivatization or drying. Automation of SIFT-MS creates a high-throughput analytical tool that addresses these throughput challenges.

In this webinar, we demonstrate the advantages of applying automated SIFT-MS to analysis of volatiles in diverse matrices, from air to the headspace of polymers, soil, and water. Formaldehyde and the BTEX compounds (benzene, toluene, ethylbenzene and the xylenes) will be utilized in various case studies. For the first time with direct MS, we present a calibration approach that enables speciation of ethylbenzene from the xylenes in real time.
