Hitachi Amino Acid Analyzer
Hitachi Updated: 2008-09-03 RSSHigh Speed Amino Acid Analyzer from Hitachi
Hitachi has manufactured over 1800 Amino Acid Analyzers for over40 years. The L-8900 is capable of analyzing physiological fluids and protein hydrolysates. If you have special requirements, the L-8900 is the one to choose! Hitachi offers the best solution to amino acid analysis.
High Sensitivity: Reaction Column vs. Reaction Coil:
In conventional analyzers, sample zone spreading within the reaction coil causes adverse effects on separation. The L-8900 features a special reaction column (patent pending) to maintain good separation of the sample zone and yet offering high sensitivity and high-speed analysis.
Front Access
No space is needed at the side of the instrument for maintenance. Just open the front door to replace consumables, columns and the liquid waste container.
No Need for Refrigeration
The L-8900's unique post column delivery design mixes the two ninhydrin reagents just prior to amino acid derivatization. This means they can be stored for a year without refrigeration.
