ARACUS works on the principle of golden standard, the post-column derivatization with ninhydrin, and the detection at 440nm and 570nm using maintenance-free LED photometers.
With a separation of more than 50 amino acids by cation exchange chromatography and a detection limit of < 2 nmol/mL, ARACUS offers the customer a wide range of application fields:
- 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)
ARACUS 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
