FlavourSpec to detect Volatile Organic Compounds
Gas Chromatography-Ion Mobility Spectrometer for the Detection of Volatile Organic Compounds in Food and Beverages
The FlavourSpec¢ē represents the synergies of a fast gas chromatograph and the outstanding sensitivity of an IMS.
It enables the selective detection of Volatile Organic Compounds (VOCs) in the headspace of solid and liquid samples.
As result a 3 dimensional spectra as characteristic fingerprint of the sample is achieved and further analysed using multivariate data analysing tools.
To make the operation of sampling and processing simple and easy the system is set up with an automatic GC headspace injector.
