Multi-Desorption mode TD and enrichment for maximum sensitivity

Automated Multi-Desorption Mode is available for the GERSTEL Thermal Desorption System (TDS) and GERSTEL Thermal Desorption Unit (TDU).

Analytes from a number of sample extractions can be desorbed and concentrated for each GC/MS run, significantly increasing sensitivity and reducing limits of determination.

Multi-desorption mode is activated by simple selection in the MAESTRO configuration editor. In the sequence table, desorption of multiple adsorbent tubes or Twisters for every GC/MS run can then be specified. Individual tube numbers or ranges can be chosen freely.

For SBSE analysis, system sensitivity has been shown to be proportional to the number of Twisters desorbed.
