Unity 2

Universal thermal desorption unit for sorbent tubes

UNITY™ is an industry-leading analytical thermal desorption instrument for the simultaneous analysis of VOCs, SVOCs and thermally labile compounds collected onto sorbent tubes. 

In contrast to other thermal desorption units, UNITY quantitatively re-collects the thermally desorbed sample for re-analysis or storage, enhancing sample security. UNITY also features an electrically cooled cold trap, dispensing with the expense and inconvenience of liquid cryogen. 

Product benefits

    • Reduce running costs by avoiding the need for cryogen.
    • Enhance productivity with the world’s most versatile thermal desorber – UNITY offers unmatched analytical performance for the widest range of TD applications.
    • Peace of mind – with quantitative sample re-collection for repeat analysis, UNITY offers simple method/data validation and overcomes the ‘one-shot’ limitation of other systems.
    • Future-proof your lab – you are buying the leading-brand thermal desorber and a perfect platform for expansion as the needs of your lab grow.
  • Be confident – you’re using a desorber that complies with key standards such as US EPA Method TO-17.


  • Simultaneously analyse the broadest range of analytes from C2 to n-C40 and thermally labile compounds. 
  • Sample splitting allows compatibility with high- and low-concentration samples (low-ppt to percent). 
  • Cryogen-free operation reduces running costs. 
  • Quantitative re-collection of samples – allowing sample re-analysis. 
  • Complies with international standard methods. 
  • Each sample leak-tested to ensure accurate results. 
  • Fully upgrade UNITY to multi-tube, multi-canister or on-line capability. 
  • Designed for easy maintenance. 
  • Easily integrates into any laboratory – combines with any make of GC. 
  • Advanced capabilities include – easy-change focusing trap, compatibility with TubeTAG electronic tube labels, options for 4.5-inch (DAAMS) tubes and compatibility with electronic carrier gas control.
