- Extra small eluent consumption
- Pump allows the simultaenous operation of two fluicid lines
- Manual injection mode
- Easy access to all components of the entire system
Method
Post column derivatization with ninhydrin
Reproducibility of retention time & area:
< 0.3 % RSD
ca. 1 % RSD
Detection limit
< 2 nmol/mL
Reliable analysis results for a wide range of applications
Qualitative and quantitative analysis of amino acids is required for a wide range of applications. Our ARACUS systems are designed for use in clinics, quality control, the pharmaceutical and food industry as well as in research. The ARACUS AA analyzers use the most precise and reproducable methodology, with which you can get up to 44 AA with an “Retention time reproducibility (RSD)” of less than 0.1%. Choose your desired configuration with the aracus lite, classic and advanced – depending on the complexity of your amino acid analyses.
Amino Acid Analyzers for all major lab applications
- 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 / choice of two sensitivity detector levels
- Level sensors for eluents / warn the user if needed fluidic volume is too low for planned analysis
- Easy access to all components of the entire system
Autosampler
The ARAUS lite can be upgraded later on with autosampler.
High pressure side prime and purge valves in eluent and reagent flow.
Validation documents IQ/OQ and PQ for ARACUS.
Manual and automatic peak integration with integrated IQ/OQ procedure for software (only available with software Clarity).
It supplies the main unit and eluent box with a protective gas atmosphere by reducing the presence of atmospheric oxygen to enhance the signal to noise ratio.
The existing 500 or 570 nm photometer will be replaced by a photometer with 440 nm and 570 nm wavelength.
