High-Speed Amino Acid Analyzer LA8080 AminoSAAYA
Developed with the user in mind, the AminoSAAYA offers easy and comfortable operability while maintaining the reliability and stability of Hitachi’s legacy amino acid analyzers.
Features
The Hitachi LA8080 AminoSAAYA combines a dedicated ion-exchange column with modules optimized for amino acid analysis.
Ergonomic Design
The height of the reagent setup unit was adjusted for better accessibility, making daily tasks such as reagent replacement, sample setup, and maintenance easier. Work performed in a half-sitting position has been minimized (the front door is also removable).
Space-saving compact design
A compact desktop-type system was realized, with the system setup area reduced by about 30%. The reliability and stability of the dedicated system remain unchanged.
Reliable post-column ninhydrin method
The analysis methods are inherited from previous models (L-8800/L-8900). The basic analytical conditions, columns (packing materials), and reagents that have been in use can be used without making any changes
Ready-to-use reagents, no refrigeration
Commercially available dedicated reagents can be used without preparation. The two ninhydrin solutions are mixed immediately before the derivatization reaction, so there is no need for refrigeration.
Flexible analysis methods
Select the analysis method (column, reagent, and analytical conditions): Protein Hydrolysates (PH) or Physiological Fluids (PF). Up to 6 buffer solutions and a column oven with time programming allow methods to be built for your purpose.
