Abstract
Direct Sampling Ion Trap MS (DSITMS) is an environmental sampling and analysis system designed for simplicity, the combination of a rugged MS with both high sensitivity and selectivity, with a simple sampling and analysis system. Sampling devices developed for use with DSITMS include a soil/water purge module for VOC in discrete water and soil samples, an in situ sparge module for VOC in wells, in subsurface water via push pipes, and in surface bodies of water, a water atomizing spray module for real-time analysis of VOC in process streams, a real time air monitor for analysis of VOC, and a thermal desorption module for analysis of collected sorbent samples of VOC and SVOC. This collection of sampling devices allows for rapid or real time analysis of VOC in water, soils and sludges, and gases with no chain of custody and no sample acquisition or disposal for some methods. DSITMS has been used in > 60 field deployments around the US for rapid qualitative and quantitative analysis of environmental samples from various matrices. Sampling has included monitoring and depth profiling of wells, real-time sampling of automobile exhaust, real-time characterization of on-site remediation processes, multiple site characterizations, and stack emissions from incinerators.
