Universal Thermal Desorption Instrument for Simultaneous Analysis of VOCs, SVOCs and Thermally Labile Compounds

Markes’ UNITY is an advanced analytical thermal desorption instrument designed for real-time analysis of SVOCs, VOCs and thermally labile compounds accumulated onsorbent tubes.

UNITY, contrary to other thermal desorption units, quantitatively re-collects samples for storage or re-analysis and thus improves sample security. It also includes an electrically cooled cold trap that eliminates the cost and inconvenience associated with liquid cryogen.

Key Features and Benefits

The main features and benefits of the UNITY analytical thermal desorption instrument are:

Simultaneous analysis of analytes from C2 to n-C40 and thermally labile compounds

Cryogen-free operation reduces operation costs

All samples leak-tested for accurate results

Quantitative re-collection of samples enables sample re-analysis or storage

Sample splitting enables compatibility with high- and low-concentration samples (low-ppt to percent)

Electrically cooled cold trap

Designed for easy maintenance

Easily integrates into laboratories, combines with any make of GC

Fully advance UNITY to multi-tube, multi-canister or on-line capability

Easy-change focusing trap

Advanced capabilities: Compatible with TubeTAG electronic tube labels, options for 4.5-inch (DAAMS) tubes and compatible with electronic carrier gas control

Provides easy method/data validation and overpowers ‘one-shot’ limitation of other systems

Improves productivity

Complies with key international standards such as US EPA Method TO-17
