Automatic amino acid analyser AAA 400

Automatic amino acid analyser AAA 400

AAA 400 Automatic Amino Acid Analyser is used for determination of amino acids in protein and peptide hydrolysates, for the dermination of free amino acids in physiological liquids and extracts as well. These characteristics determine AAA 400 for wide use in basic biochemical research of proteins, in research of human and animal nourishment, in medical diagnostics, in testing of drugs etc.

Here is at disposal collection of examples of analyses in format pdf. To view the example analyses is necesary Adobe Acrobat Reader, which can be downloaded free of charge from Adobe company sites.

The analysis is based on medium pressure ion-exchange chromatography with the colorimetric detection.

The computer controls all processes and secures all checking operations and evaluations of results which can be printed as protocols.

We offer all chemicals and standards necessary for the operation of the instrument.
