Fully automatic Amino acid analyzer
(highest precision - easy handling)
- with inert gas supply
- autosampler with 4x48 Standard vials or 4 micro plates
- online peak identification
The amino acid analyzer ARACUS with its modular concept is the ideal instrument for the analysis of amino
acids in research, quality control and in the clinical laboratory.It combines innovative technologies with the classical routine analysis of amino acids by the post- column derivatisation with ninhydrin.
This produces on the day by day use results with the highest precision, reproducibility and accuracy.
The setup of the instrument allows the continuous analysis of up to 192 samples (4 x48 vials, autosampler option 1) or 96 samples (2 x48 vials, autosampler option 2).
The samples are stored in the cooled autosampler and the samples are injected without sample loss.
A washing routine of the injection valve and syringe pump guarantees zero cross-contamination.
As a third option the ARACUS instrument is available with a manual injection system.
The eluent rack contains 6 glass bottles. The fluid volume of each bottle is actively monitored during
Eluents, ninhydrin and washing reagent are selectively chosen through buffer selection valves and degassed in micro vacuum chambers. The innovative technology of the pump allows the simultanous operation of two fluid lines (eluent side and reagent side), which guarantees a constant mixing.
The maintenance free photometers detect the separated amino acids at 570 nm and 440 nm and the signals
are registered by the software aminoPeak.
The concept of the ready-to-use eluent and reagent kits allows the reproducible analysis of the amino acid
samples. Each kit is produced under standardized procedures, tested and certified before shipping.
Depending on the application, the eleunt and reagent kit contains the necessary amount for 500 or 1000
ARACUS is operated with the user friendly, self-explanatory software iControl. Implemented, optimized separation programs are correlated with each sample for the analysis. Correlation with new samples can be done when the instrument is analyzing a sample. The current status of important instrument parameters
is shown as well as the fluid volumes of each eluent and reagent bottle. As soon as a minimal value is reached, different alarm levels inform the operator. All operation parameters and events of each analysis
are documented in a log-File.
