Olfactometer
In gas chromatographic analyses flame ionization detectors (FID), thermal conductivity detectors (TCD) or mass spectrometers (MSD) are often used for compound detection. In olfactory analysis, the human nose is used as additional detector.
The JAS Olfactometer is a sniff detector for gas chromatography. It allows the operator to use his human nose to identify single odors as they elute from the analytical column. Olfactory events are digitally recorded by intensity and duration. This allows the user to identify single odors in complex smells.
The Olfactometer in detail
After separation on the analytical column the effluent is split and simultaniously guided to a detector (FID, TCD or MSD) and the nose piece of the JAS Olfactometer.
The operator uses a unique pusher/slider combination to mark peaks by their appearance, intensity and duration in the Agilent OpenLAB CDS ChemStation, MSD ChemStation or OpenLAB CDS EZChrom Software.
By combining the human nose and e.g. a FID, the user receives information about the aroma quality of the eluting compounds and the composition of the sample simultaneously.
