Trace Detection of Flavour inducing Volatiles without Sample pre-treatment

G.A.S. instruments use the selectivity of gas chromatography and the outstanding sensitivity of ion mobility spectrometry to test food, flavour and beverages as they are. The combination of both physical working principles secure highest reproducibility and either by quantification of marker compounds same as fingerprint analysis allow a and reliable and impartial flavour analysis and documentation.

Sensitive Testing of Mal-odours, Toxic Compounds in Air and Industrial Gases

Separating the often difficult matrix by gas chromatography coupled to ion mobility as detector technology, G.A.S. succeeds in developing customized instruments that detect and quantify hazardous or unwanted compounds at low ppb-level in air or gases.

Human Breath Analysis

G.A.S. instruments are suitable to directly sample from human breath and measure volatile organic compounds (VOC) in exhaled air. Using a GC-IMS set-up the humid matrix is separated and compounds of interest related to intoxications and diseases can be measured at trace (ppb-) level without pre-concentration.
