Amino Acid Analyzer

Amino Acid Analyzers

The ARACUS is a dedicated amino acid analyser for high end analysis of amino acids in research, food quality control (own patent 10 2016 010 887), beverages and feedstuff and in the clinical laboratory. It combines innovative technologies with the classic routine analysis of amino acids by post-column derivatization with ninhydrin and the detection at 440 nm and 570 nm using maintenance-free LED photometers.

The setup of the instrument allows the continuous analysis of 96 samples (2 x 48 vials) in a cooled autosampler. The pump allows the simultaneous operation of two fluid lines (eluent line and reactive line), which guarantees a constant mixing. Eluents and reagent solution are selectively chosen through valves and are ideally mixed to each other. The addition of ninhydrin provides a quantitative analysis statement.

Applications

• Determination of free/physiological amino acids in blood plasma, dried blood spots, serum salvia, and urine (e.g. New Born Screening)
• Determination of hydrolyzed amino acids in food, beverages, and feedstuff
• Determination of biogenic amine for the investigation of metabolic processes (plants animals, humans)

Advantages

• Detectors with maintenance-free LED technology (440 & 570 nm) - no UV/VIS lamp degeneration and lamp exchange
• Chloride-free and citrate-free buffer system - Less aggressive to the components of the liquid handling tubes, fittings, and connection
• Small eluent consumption - About 200 µL/min in analysis mode
• High sensitivity of amino acids and a choice of two sensitivity detector levels
• Level sensors for eluents - Warn the user if the needed fluidic volume is too low for the planned analysis
• Easy access to all components of the entire system
