Gas Chromatography Olfactometry (GC/O) of Dairy Products
International Dairy Journal, 1998 Abstract Analysis of the aroma of dairy products is a complex problem due to the heterogeneous nature of milk. Several analytical methods have been used to study the aroma of dairy products; gas chromatography–mass spectrometry (GC/MS) and gas chromatography– olfactometry (GC/O) are most commonly used.

Gas chromatography‐olfactometry [PDF]
Journal of Separation Science, 2006 AbstractGC‐olfactometry (GC‐O) refers to the use of human assessors as a sensitive and selective detector for odour‐active compounds. The aim of this technique is to determine the odour activity of volatile compounds in a sample extract, and assign a relative importance to each compound.

Effects of the Sniffing Port Air Makeup in Gas Chromatography−Olfactometry [PDF]
Journal of Agricultural and Food Chemistry, 2000 A time-intensity gas chromatography-olfactometry (GCO) apparatus was developed to study some aerodynamic parameters that may influence odor detection and intensity measurements by the subjects. The addition of humidified air at the elution place of the compounds is generally recommended for several reasons (essentially to prevent nasal mucosa ...
