Reducing the helium consumption for analysis of VOCs in accordance with EPA Method 8260D without compromising performance using HeSaver-H2 Safer technology

15 Mar 2024

In this application note, Thermo Fisher Scientific discusses the significance of volatile organic compounds (VOCs). The method of choice for analyzing VOCs involves gas chromatography coupled with single quadrupole mass spectrometry using Purge and Trap (P&T) sampling. The HeSaver-H2Safer™ technology offers a solution by significantly reducing helium consumption without compromising performance. The application of this technology in conjunction with gas chromatography and mass spectrometry for the analysis of water and soil samples according to EPA Method 8260D is detailed. The results demonstrate that the HeSaver-H2Safer™ technology allows for minimal method transfer effort while maintaining chromatographic performance across different matrices.

Atomx XYZ Automated VOC Sample Prep System

Teledyne Labs

Tekmar's  Atomx Automated Sample Prep System combines an Autosampler and Purge and Trap into a single instrument for the analysis of VOCs in soils and waters. This is the first of its kind and only system that employs a unique methanol extraction automation feature for high level soils in accordance with USEPA Method 5035.   Extractasol clean-up step (patent pending) in the Atomx reduces carryover or cross contamination normally associated with high-level water or soil analysis. Three new independent injection systems for internal standards, surrogates, and matrix spikes provide the ability to select variable volumes without generating waste. The Atomx features Tekmar’s proven carousel drive capable of holding 80-vials for optimal throughput therefore reducing downtime. While priced competitively, this system offers unique features that cannot be found on other sample prep systems on the market today.
