HiSorb is an innovative labour-saving sampling system for the analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs) in liquids and solids by TD–GC–MS. HiSorb can be used for headspace as well as immersive sampling. * Detection limits are lower than for SPME because of the larger capacity of sorptive phase * Easier and quicker to use than solvent extraction * Re-usable probes and tubes minimise the cost per sample * Robust and easy to use with multiple phases available * Simple and elegant design when working with opaque or dirty liquids Extending the capability of thermal desorption (TD), HiSorb probes and accessories are ideal for trace-level component characterisation, aroma profiling, quality control and advanced research across a wide range of applications. HiSorb is suitable for existing thermal desorption users wishing to extend their capabilities to extraction from liquids, as well as users of headspace, solid-phase microextraction (SPME) or liquid extraction wanting to enhance the characterisation of their samples or obtain complementary information.

Chemical analysis using thermal desorption & GC-MS. There is absolutely no need to compromise on sample security and risk your data. ‘Sample security in 60 seconds’ – in the video below, we explain how the valve and trap in every Markes thermal desorption system enables sample re-collection – overcoming the ‘one-shot’ drawback of other manufacturers’ TD systems. Meaning that your valuable samples can be secured and quantitively re-analysed.
