Enjoy the enhanced benefits of:

 Extended re-collection – Sample security

  • Improved re-collection allowing valuable samples to be re-analysed, overcoming the historic ‘one-shot’ limitation of thermal desorption
  • Allows complete analyte transfer to be validated, ensuring compliance with standard methods
  • Allows Hi/Lo analysis of concentrated samples to quantify both percent level and trace compounds from the same sample!

Cost saving

  • Option to use cheaper alternatives to helium such as hydrogen, nitrogen or even continue using helium until you’re ready to make the switch. PLUS: Shorter run times with option for hydrogen carrier
  • Cryogen-free operation: the -xr series continue to successfully use Peltier cooling to trap analytes

Extended analyte range

  • Inert flow path and backflush operation allows a wide analyte range of C2-C44 allowing analysis of acetylene to PAHs, PCBs and phthalates
  • Effective water removal for analysis of alcohols, oxygenates and pinenes from humid samples


  • Automated addition of an internal standard to the focusing trap, or to a tube, during analysis enhances the quality of your data

High data quality

  • Sample stacking to improve sensitivity for ultra-trace compounds
  • Automatic leak tests carried out before analysis of each sample ensure confidence in your data quality

Extended reliability

  • Improved water management options with elevated trap purge and option of Kori-xr for selective water removal for online and canister/bag samples
  • Increased fault detection with automatic recovery and serviceability
