The determination of odor threshold values can be performed in various matrices, including air, and serves as a parameter to compare the potencies of odorous compounds. Typically, the odor thresholds in air are determined by gas chromatography-olfactory (GC-O) and referenced to an internal standard, most often ( E )-dec-2-enal. Herein, a direct gas chromatography-flame ionization detector-olfactory analysis method for the determination of odor thresholds in air is reported. As model substrates for this novel approach, naturally occurring substances ( R )-1- p -menthene-8-thiol as well as (3 S ,3a S ,6 R ,7a S )-3,6-dimethyl-3a,4,5,6,7,7a-hexahydro-3 H -1-benzofuran-2-one were used...
