Simply perfect and reliable

 

Average Rating 5.0

Application Area:

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.

Application Area:

Analyze ambient air

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

UNITY-xr is the most versatile thermal desorber for the analysis of VOCs and SVOCs in air and materials.

Features:

  • Compatible with all major makes of GC and GC–MS
  • Quantitative recovery of C2 to C44, including reactive and thermally labile species, from percent to sub-ppt concentrations
  • 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
