Sorptive extraction

High-capacity sorptive extraction is an innovative, labour-saving sampling approach to the analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs) in liquids and solids by TD–GC–MS.

Extending the capability of thermal desorption (TD), Markes International's HiSorb™ probes and accessories are ideal for trace-level component characterisation, aroma profiling, quality control and advanced research across a wide range of applications. Full automation of HiSorb is now possible on Markes' Centri^® platform.

Why use HiSorb sorptive extraction?

• Robust, easy-to-use probes allow unattended sample preparation and maximum productivity.
• Simpler and quicker to use than solvent extraction.
• Reduce costs associated with solvent consumption and disposal.
• Re-usable probes and tubes minimise the cost per sample.
• Improved detection limits over SPME due to the larger capacity of the PDMS sorbent.
• Cryogen-free pre-concentration by TD prior to automated GC–MS analysis improves sensitivity.
• Flexible sampling (immersive or headspace) for both liquid and solid samples.
• Compatible with industry-standard TD tubes on all leading commercial systems.
