Biochrom
Amino Acid Analyzer System, to monitoring and analyzing proteins, peptides and other ingredients in foods, beverages and livestock feed, to optimize nutritional value of your products, making them healthier to consume. The ability to accurately qualify and quantify amino acids at a molecular level is essential using gold standard techniques, the only one system established in the world. This system is exceptionally crucial to use in the lab where highest quality is to be achieved. All chemicals and standards are available at highest quality control to support the AAA system worldwide.
