High-Speed Amino Acid Analyzer L-8900

Our Amino Acid Analyzer, Model L-8900, is the culmination of the technology and expertise earned through our extensive experience in manufacturing amino acid analyzers for over 50 years.


Unparalleled detection limits can be achieved — 3 pmol of aspartic acid using ninhydrin reaction methods.
Standard amino acid determination takes just 30 minutes (net) and physiological fluid determination is carried out fully automatically in just 110 minutes.

Agilent OpenLAB CDS EZChrom Edition for easy Operation

The L-8900 is controlled with Agilent OpenLAB CDS EZChrom Edition and supports chromatography systems from multiple manufacturers (the software has over 30,000 users worldwide).
