Ion Chromatography: A Versatile Technique for the Analysis of Beer
Ion Chromatography: A Versatile Technique for the Analysis of Beer
30 Jun 2016The compounds of interest for the beer industry range from inorganic ions and organic acids that contribute to the overall taste and bitterness of the beverage, to proteins, carbohydrates, and alcohols that are monitored to determine the extent of fermentation. Ion chromatography is an efficient technique for the analysis and quantification of ions in solution and is rapidly becoming the method of choice. This application note describes the use of ion-exchange or ion-exclusion chromatography for the determination of five classes of compounds of interest to the brewing industry, including carbohydrates, alcohols, organic acids, inorganic anions, and inorganic cations.

Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Protein QuantificationThe detection and quantification of proteins in a sample is vital across life sciences, pharmaceutical research and clinical diagnostics, and a variety of equipment is available to scientists to simplify the workflow. Proteins of interest can be easily labeled and detected on light-based detection instruments. Immunoassay kits allow you to identify a specific protein of interest and protein detection beads or antibody microarrays allow you to identify multiple specific proteins at once. Protein interactions and enzyme activity can also be monitored with protein-protein interaction assays. Additionally, the biophysical characterization of proteins is made easy with biokinetic analyzers.
