About G.A.S.

G.A.S. Gesellschaft für analytische Sensorsysteme mbH, based in Dortmund, develops and manufactures gas analyzers for trace analysis of volatile organic compounds (VOCs). The instruments combine gas chromatography (GC) with ion mobility spectrometry (IMS) and enable direct detection of trace substances in the ppb range, often without sample preparation or pre-concentration. The portfolio includes systems such as FlavourSpec for the analysis of food, flavors and beverages, GC-IMS-SILOX for siloxane analysis in landfill and biogases, as well as the Stream-Selector, an eight-channel multiplexer unit. Applications include, in addition to quality control, the detection of odors and toxic compounds in air and industrial gases as well as human breath analysis. In addition, the company offers customized solutions, including application-specific instrument configuration, individual measurement methods and user-oriented software.

Measurement Methods & Technology

GC-IMS

Gas chromatography with ion mobility spectrometry

Combination of the selectivity of gas chromatography with the sensitivity of ion mobility spectrometry for trace analysis of VOCs in the ppb range.

FlavourSpec

FlavourSpec GC-IMS analysis system

Analysis of food, flavors and beverages without sample preparation by means of quantification of marker compounds and fingerprint analysis.

GC-IMS-SILOX

Detection and automated quantification of siloxanes in landfill and biogases on site; the method is standardized as ASTM D8455-22 and ISO 2613-2.

Stream-Selector

Eight-channel multiplexer unit for sequential measurement of multiple gas streams on one analyzer.
