L-8900 Amino Acid Analyzer
High 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.
The speed of the mobile phase is highest at the center of the tube, causing peak broadening.
By filling the reaction column with beads, the mobile phase moves less smoothly, resulting in a homogeneous flow without peak broadening.
Exceptionally Fast Analysis with Outstanding Detection Limits
Standard amino acid determination takes just 30 minutes (net) and physiological fluid determination can be carried out fully automatically in just 110 minutes.
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.
Superb Separation with 3Âµm Particles
The finer the packing particles, the higher the number of theoretical plates. That means better separation. Finer particules also boost flow rate at the maximum number of theoretical plates. The 3Âµm packing particles used in the L-8900 are a key technology for fast analysis over a broad range of flow rates with excellent separation.
