Rapid Determination of Vicinal Diketones in Beer

beer

Vicinal diketones (VDK) in beer, which include 2,3-butanedione (diacetyl) and 2,3-pentanedione are the flavour components that produce a buttery or butterscotch like aroma in beer. As a by-product of the fermentation process of yeast this buttery aroma can result in an undesireable off-smell. Off line monitoring of VDK is normally undertaken off site in a specialist laboratory, extending brewing times prior to filtering and bottling. Production requirements for the beer industry necessitate […]

Analysis of VOCs in Biogas

Analysis of VOCs in Biogas

Natural gas is generally odourless and easily detected through the presence of odourants such as THT (tetrahydothiophen), Gasodor S-Free (methyl- and ethylacrylates) and TBM (tert-Butylthiol). The presence of odourants is important for detection of leaks which can be a safety issue. Biogas produced by fermentation of organic sources contains volatile organic compounds (VOC) either from […]
