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).
