Next to water, protein is the most abundant substance in the body. A standard solution containing a known amount (500 pmol) of 17 common free amino acids is also loaded on a separate amino acid analyzer sample spot and derivatized.
Different proteins vary in the order and number of amino acids in their polypeptide chains. The buffer flow rate was 30 mL/hour, so basic amino acids were analyzed in the morning, and neutral and acidic amino acids were analyzed in the afternoon. 9 cm, and was 15 cm long; and a long column, for neutral and acidic amino acid analysis, that was 150 cm long. Food supplements analyzed were tablets of Amino Acids Complex (AAC), and capsules of Branched-Chain Amino Acids (BCAA) and Taurine and L-Theanine complex (TTC) from VITALL +® (Etik & Bio, France).
Hitachi&39;s New Amino Acid Analyzer, Model L-8900, is the culmination of the technology and expertise earned from our extensive experience in manufacturing amino acid analyzers during the past 40 years. The basic principle of this analyzer has hardly been changed in the amino acid analyzers that are currently in widespread use (see below), and, as a general analysis method for the amino acids making up proteins, it has been found to be much better than the methods that were in previous use, in terms of sample volumes, analysis operations, etc. In order to separate amino acids for analyses, we have to exploit very.
