Sniffer 9000
The GC-Olfactometry is in theory a simple method. At the end of a chromatographic column a split is installed and allows the sample to be splitted (e.g. 1:50) FID Detector/nose. The peak/odor impression correlation will then be performed by specialized fragrance chemists. The heart of the Sniffer 9000 technology is the dedicated GC/Olfactometer heated Interface.
Brechbühler AG has over 35 years experience in implementing hyphenated techniques by using special designed interfaces. The Sniffer 9000 interface is engineered to transfer the high resolution available on capillary columns to the olfactometry "Sniffing Port" without loss of GC resolution and influence of oxidation or turbulence.
Built as part of the current Sniffer 9000 System, the interface is manufactured from a single Stainless steel tube which is heated by direct current, thus giving the best possible temperature profile. The interface consists of a standard fused silica line resulting in an inert olfactometer interface.
Engineered to combine hot column effluents with laminar streams of inert make-up gas generated by the Sniffer 9000 System and additional humidification air supply to deliver distinct odours to humans subjects with minimum discomfort and maximum separation. Integrated into any GC System available on the market.
A special analogous output allows the Sniffer 9000 to be connected to an additional Channel on an existing data system, or any integrator or recorder available in the lab, to record intensity via the integrated cursor wheel on the Hand-held Remote control unit.
The SNIFFER 9000 "Finger Span" option is a additional mechanical device which allows the intensity indication to be adjusted to the individual distance between the thumb and another finger of the panelists indicating their impression of the odor of the components.
Available in 2 length: 80 cm and 140 cm.
