Enrichment and Desorption Unit - Trap/Thermal Desorption
The EDU-GC3 is one instrument from the successful series of Trap and Thermal Desorption solutions from Airsense optimized for operations with standard laboratory gas-chromatographs.
The enrichment and desorption unit works fully automatically. The easy coupling to all gas chromatographs and to the different adsorbents make out of the EDU-GC3 a very flexible system.
This autonomous device is able to gather, desorb, inject and clean for multiple cycles automatically. Through the adsorption process it is possible to concentrate organic compounds or a range of analytes by performing their separation from the common interfering substances. Depending on the parameters of analysis and also on the target substances it is possible to improve the detection limits to a certain order of magnitude. For the analysis with gas chromatographs there is the additional advantage that common interfering compounds, like water in environmental probes can be extracted almost completely from the sample. Different variants from this unit are available.
Important features of the EDU-GC3:
Improvement of detection limits
Water fade out
Automatic cycles from Enrichment until desorption
Simple change of adsorbent tubes
Programmable and independent operation
Variants for different GC- manufacturers available
