An advanced, method-compliant thermal desorption system for continuous low-flow environmental monitoring of trace-level volatile and semi-volatile organic compounds by GC–MS.

Discover the applications for a variety of sorbent tubes and focusing traps.

Thermal desorption tubes for optimum sampling and analytical performance.

Patented TubeTAG™ system that enables tube history and sample information to accompany a tube throughout its lifetime – a sophisticated solution for tracking tubes during field monitoring projects.

An accessory that can be added to any manual UNITY™ thermal desorption platform to provide a simple and convenient mechanism for direct introduction/‘on-line’ sampling of headspace vapours from a wide range of bulk sample containers.

A 100-tube autosampler enabling high-productivity analysis of trace-level VOCs and SVOCs with GC or GC–MS.

A robust autosampler for unattended on-line monitoring of ambient air or industrial processes. 

Cryogen-free, automated whole-air preconcentration system. 

Multi-tube thermal desorber with advanced re-collection options.

Single-tube thermal desorption unit, delivering exceptional GC(–MS) performance for industry-standard-sized sample tubes and offers unmatched upgrade flexibility for tube, canister and on-line automation.

A stainless steel assembly that is inserted into the ground, allowing soil gas to be sampled onto a sorbent tube, for analysis by thermal desorption (TD)–GC.
