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 on sorbent 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
