Head-space analysis in brewing analytics.

Abstract

Head-space gas chromatography is a sample preparation method for determination of volatile compounds. This technique is very often used in food analyses including beer. This paper is focused on application of this procedure in brewing analytics. Advantages and disadvantages of this method in different modes - static head-space (gastight syringe based system or valve and loop based system) and dynamic head-space (purge and trap) are discussed.Head-space gas chromatography is a sample preparation method for determination of volatile compounds.
