Multi-Desorption Mode TD

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 into a single GC/MS run, significantly increasing sensitivity and reducing limits of detection. Multidesorption 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, peak areas have been shown to be proportional to the number of Twisters desorbed.
