Gas Chromatography - Olfactometry, Sniffer. GC-O.
Gas Chromatography - Olfactometry. Here you find the best GC-O unit or also called Sniffer. The instrument fits to any Gas Chromatograph. The human nose is an incredible detector for aroma/mal-odour components. Gas Chromatography Olfactometry (GC-O) is a bioassay that measures human response to odorants separated by gas chromatography. The superior sensitivity and selectivity of human olfaction make GC-O a powerful and meaningful tool for flavour chemistry. Head-space sampling, distillation, solvent extraction, solid phase micro extraction (SPME) and our DMI are typical procedures used to introduce samples in a GC-O. Besides providing data about the potency of odorants extracted and separated for samples, GC-O can also be used to study variation in human olfaction or provide testing and training of panellists used in sensory testing. At its best, GC-O, provides industry with a link between chemical data collected from ingredients or products and the sensory and consumer preference data collected from the market place. At the very least GC-O data derived from a product can be used for quality control or the development of value added products.

Gas Chromatography - Olfactometry (GC-O or Sniffer) GL Sciences B.V. | De Sleutel 9, 5652 AS Eindhoven, The Netherlands |Phone: +31 40 2549531 | info@glsciences.eu |www.glsciences.eu The human nose is an incredible detector for aroma/mal-odor components. The sensitivity and selectivity are equal or better than the available GC detectors. Gas Chromatography - Olfactometry (GC/O) is the collection of techniques that combine Olfactometry or the use of human detectors to access odor activity in defined air streams with the Gas Chromatographic (GC) separation of volatiles.

PHASER – Gas Chromatography Olfactory Port GL Sciences B.V. | De Sleutel 9, 5652 AS Eindhoven, The Netherlands |Phone: +31 40 2549531 | info@glsciences.eu |www.glsciences.eu PHASER is an advanced sniffing port, through which an analyst using his/her sense of smell can efficiently sense and identify flavor and fragrance components separated by a gas chromatographic column. A column effluent is directly transferred to a PHASER nose cone through deactivated fused silica tube allowing the operator to smell the compounds that exit the column. Why PHASER? No-cold-spot design provides possibility to sniff high boiling compounds Transfer line temperature up to 300 ˚C Operator nose protection by adding moisturized air to sniffing port Easy-connect SilFlow™ micro-channel device as column flow splitter Sitting or standing while sniffing Compact and easy-to-install on any type of GC Voice recording with replay function and voice recognition With or without MS detector SilFlow is a trademark of SGE
