GC-O refers to Gas Chromatography coupled with Olfactometry. A human (panelist) is one of the detectors and works in parallel with a GC detector. GC-O combines human perception and scientific response to help professionals link chemical compound to the emotional sense elicited by the said compounds. It allows one to characterize the ﬂavors and fragrances and identify specifc chemical compounds within them. GC-O exhibits powerful capabilities that can be applied to ﬂavors and perfumes, as well as to any odoriferous products (e.g. pollutants) The Sniffer 9100 System is designed to be a dedicated Sniffng-port as a stand alone unit to be connected to any GC available on the market. It is also available as a complete system.
GC-Olfactometry theory is simple. By installing at the end of a chromatographic column a split, the sample is splitted between the FID Detector and the nose. The peak/odor impression correlation will then be performed by specialized fragrance chemists.
