Markes Kori-xr Water Abstraction Device

The Markes Kori-xr is a novel water management solution for canister and on-line monitoring.
The Kori-xr water abstraction device delivers outstanding results for on-line and canister analysis of humid air by TD–GC–MS without any need for liquid cryogen. The efficient removal of water by Kori-xr permits lower temperatures to be used in the focusing trap without risk of ice formation, allowing quantitative retention of VOCs, VVOCs, oxygenates and monoterpenes on the UNITY-xr™ thermal desorber. Kori-xr is an add-on accessory for the CIA Advantage Automated Canister Analyzer or Unity-Air Server-xr Online Analysis.

Features

  • Electrically-cooled (no cryogen) trap selectively removes water from the sample stream before it enters the focusing trap.
  • Allows simultaneous, quantitative analysis of C2 compounds, VOCs, VVOCs, oxygenates (OVOCs), monoterpenes and other polar species.
  • Compatible with gas-phase samples ranging from below ambient pressure to 50 psig.
  • Permits lower trapping temperatures without the risk of ice formation.
  • Improved detection limits to 10 ppt or less with regular GC–quad MS – far exceeding all standard method requirements.
  • Intuitive control software: Markes Instrument Control (MIC).
