Kori-xr™ is a module that efficiently removes humidity from canister or on-line samples acquired using Markes International’s UNITY-xr systems, without affecting analyte recovery.
It’s ideal for laboratories needing to carry out on-line or canister analysis of humid air streams while avoiding the loss of polar species, oxygenates and monoterpenes that can occur with other approaches to water management.
Key features:
-
Improved performance: using Kori-xr results in better chromatography for C2 compounds, non-polar C3+ compounds, monoterpenes and polar VOCs in humid environments, compared to a Nafion™ dryer or a trap temperature of 25°C
- Easy system integration: Kori-xr is compatible with UNITY-xr systems configured with Air Server-xr or CIA Advantage-xr modules
- Selective water removal: an electrically-cooled trap selectively removes water prior to analyte focusing. Trapped water is then expelled at the same time as sample desorption from the UNITY-xr focusing trap, without increasing sampling or analysis times
- High sensitivity: part-per-trillion detection limits are easily achievable when used in conjunction with regular GC–quad MS
- Better productivity: simultaneously analyse very volatile organic compounds and polar & non-polar species.
