AMINO ACID ANALYZER         CHROMATOGRAPHY SYSTEM
 
 
Amino Acid Analyser
 
MODEL DESCRIPTION - ITEM NUMBER 600-0041
The ARACUS is a fully automatic, dedicated analyser for determination of amino acids. The method of choice is the post-column derivatization with Ninhydrine which is the gold standard for Amino Acid Analysis.
The ARACUS consists of three individual units:
(1) Autosampler:
- Sample rack for 2 x 48 1.5 ml standard vials
- Individual temperature control of each rack between 4C and 40C by Peltier elements
- Sample dosage: 1-30 l in 1l steps free programmable
- Pressure sensor control for injection needle
- Easy teach function for different sample holders
(2) Main Unit:
- Double piston pump: each piston operates one separate fluidic line (Buffer line and reagent line)
- Column heating system: Temperature range 20 - 100C, temperature accuracy 0,1C by PELTIER elements
- Reactor for ninhydrine reaction and temperature range 50 - 150C
- Micro Photometer, maintenance free and wavelength 570 nm, 440 nm
(3) Eluent Rack Elubox:
- Contains 6 bottles; each 500 ml volume
- With or without inert gas system available
- Active degassing system
System Operation Control: By external computer and 32 bit operational software iControl
