Amino acids are building blocks of the proteins, which are essential for organisms. 20 amino acids are decisive for the organism. 12 can be built up by the body, 8 have to be taken up with food.
As amino acids directly influence human health, their detection in many diverse samples are necessary.
The main focus in amino acid analysis is on food industries and medicine. Especially for the production of feed and subsequent controls by authorities this kind of analysis is done. Moreover amino acids are part of routine analysis of baby food and beverages (juices, wine, beer) as well as of early recognition of metabolic diseases, e.g. phenylkentonuria. Further fields of application are quality controls of infusion solutionsor drugs.
The principle: After the separation on a cation-exchange column the amino acids are derivatized online with a reagent (post column derivatization) and detected at 570 and 440 nm.
