Modular thermal desorption
Analyse single tubes. Expand as needed.
Key features
- Thermal desorption of individual sorbent or sample tubes
- Electrically cooled focusing trap down to −30 °C, without liquid cryogen
- Inert flow path for compounds from C2 to C44, depending on the method and sorbent
- Quantitative re-collection of split flows for repeat analysis
- Leak testing and electronic carrier-gas pressure control
- Expandable with ULTRA-xr for up to 100 tubes, Air Server-xr for online samples or CIA Advantage-xr for canisters
- Multi-Gas version: helium, nitrogen or hydrogen; the carrier gas and analytical system must be matched to the application.
Method development, research, and environmental, material and flavour analysis with modest sample throughput.
Terms: TD means thermal desorption: heating releases compounds collected on a sorbent tube. GC/MS combines gas chromatography and mass spectrometry. VOCs and SVOCs are volatile and semi-volatile organic compounds.
