Environmental Water and Soil

Simplified, high-throughput analysis of water and soil direct from headspace or after extraction.

 

High-throughput water analysis.

Analysis of volatile compounds in water is greatly simplified by SIFT-MS. The soft chemical ionization is robust to water and enables moist samples to be analyzed directly. This contrasts with GC and GC/MS approaches, where rigorous drying needs to be undertaken after extraction or purging and trapping. Using SIFT-MS, low ppb concentrations (in water) of hydrophobic volatiles (such as BTEX and low molecular weight halocarbons) are readily detectable without drying.

Rapid Analysis of BTEX in Water using Automated SIFT-MS

Selected ion flow tube mass spectrometry (SIFT-MS) combined with GERSTEL automation greatly simplifies analysis of benzene, toluene, ethylbenzene and the xylenes (BTEX) in water. This application note demonstrates the linearity, repeatability and sensitivity achievable with automated SIFT-MS. Automated static headspace (SH)-SIFT-MS provides sample throughputs at least three-fold higher than traditional purge-and-trap-gas chromatography methods.

Real-Time Speciation of Ethylbenzene from the Xylenes Using SIFT-MS

Direct mass spectrometry (DMS) techniques struggle to speciate ethylbenzene from the xylene isomers, yet increasingly regulators are imposing different emission and exposure limits for these compounds. This application note describes a significant breakthrough for DMS, because selected ion flow tube mass spectrometry (SIFT-MS) readily achieves direct, real-time speciation of the xylenes from ethylbenzene.
