OPTIC-Air-Analyser for very low Concentrations of VOCs in Indoor and Ambient Air

Together with ChromaVision the OPTIC-Air-Analyser has been developed for the automated, in situ, determination of airborne volatile organic compounds (VOCs) using programmed temperature vaporisation injection from a sorbent tube trap. A sorbent tube placed as an injection port liner can be repeatedly used to collect samples of air, with the trapped analytes being subsequently desorbed onto a capillary gas chromatography (GC) column without the use of intermediate cryogenic refocusing. The system does not need any liquid nitrogen or CO 2 , there is no need for adsorption/desorption tubes.

Strong points

  • On-line solution (Online Thermal Desorption GCMS)
  • Can automatically analyse up to 8 sample bags or Canisters
  • Compatible with any GC-MS instrument
  • No LN2 or CO2 needed
