Analysis of Lambic Beer Volatiles during Aging Using Gas Chromatography–Mass Spectrometry (GCMS) and Gas Chromatography–Olfactometry (GCO)

Beverages, 2020
Lambic beer is produced using spontaneous fermentation. Gueuze is a style of lambic beer that blends “young” (1 year old) and “aged” (2+ years old) beers.

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.

Analysis of α-lipoprotein cholesterol in 50 μl of plasma

Journal of Lipid Research, 1974
A micromethod for quantitation of α-lipoprotein cholesterol was devised for gas–liquid chromatography to minimize plasma sample size and facilitate lipid studies using capillary blood from children or small animals. α-Lipoprotein cholesterol was measured
