Simply perfect and reliable
Analyze VOCs and PAMS in whole air in canisters
As an Air Quality Analyst I find the UNITY-xr Thermal Desorber most suitable for the Whole Air in canisters analysis. The cryogen free setup works effectively to preconcentrate the sample air stream in GCMS giving results in trace ppb/ppt levels. The UNITY-xr is most reliable for accurate and quality data for VOCs, OVOCs, VVOCs in air.

Very good
Analyze ambient air
Good service, reliable. A major drawback is that the instrument needs to use air to purge the moisture in the Unity.

- Quantitative re-collection of split flows for easy method validation and repeat analysis of critical samples
- Electrical cooling eliminates the need for liquid cryogen
- Combines with ULTRA-xr for 100-tube automation, Air Server-xr for online analysis, and CIA Advantage for canister/bag samples
- Re-collection of all split flows to overcome the ‘one-shot’ limitation of older TD systems and compliance with international standard methods
