The ARACUS Amino Acid Analyzers:
The ARACUS Amino Acid Analyzers works according to the established gold standard of post column derivatization with ninhydrin, with detection at 440 nm and 570 nm, using maintenance free LED photometers. A separation of up to 44 amino acids in about one hour is possible. It is also possible to separate several amino acids within a few minutes. The ARACUS is used in a clinical laboratory (IVD newborn screening), in quality control for Food, Beverages, Feeds, and in Research. Any lab familiar with or having need of an Amino Acid Analyzer will find the selection of separation technologies and the compact configuration of the Aracus to be valued.
Aracus is available in three configurations: Classic, Advanced and Lite.
ARACUS CLASSIC
The ARACUS CLASSIC is the standard configuration of the analyzer series. The ARACUS CLASSIC allows the continuous analysis of 96 samples in a cooled autosampler. The pump allows the simultaneous operation of two fluidic lines (eluent side and reactive side), which guarantees a constant mixing. Eluents and reagent solutions are selectively chosen through valves and the mixture band are ideally mixed together.
The addition of ninhydrin post column provides a quantitative analysis as it mixes with the separated analytes for detection. A washing routine of the injection valve and syringe pump avoids cross contamination between samples. The level of the individual reagents can be monitored during the runs and warns the user if the quantity of eluents or reagents is no longer sufficient to complete the analysis.
ARACUS ADVANCED
The ARACUS ADVANCED is an extended configuration of the ARACUS CLASSIC by an additional second pump drive. The upgraded pump configuration allows the independent operation of two fluidic lines (eluent side and reactive side). The use of two pump drives results in an improved signal-to-noise ratio of the chromatogram. The freely adjustable parameters between the eluent and the reagent pump drives also provide the possibility of using OPA (o-Phthalaldehyde) as a post column reagent for detection of primary amines with a fluorescence detector.
ARACUS LITE
The ARACUS LITE is a simplified configuration of the ARACUS CLASSIC and is designed for a reduced number of samples and smaller available budget. Due to the small sample throughput and less eluent consumption, the bottles of eluents are reduced in size and makes it possible to store the eluent bottles inside of the main instrument device and the rack . The ARACUS LITE is using the same pump configuration for operation of two fluidic lines (eluent side and reactive side) and suitable for High Speed and High Resolution columns.
The system is equipped with a manual injection mode or can be connected with an autosampler like all our devices. The ARACUS LITE comes just with one LED photometer depending on the application. For analysis of 1° amino acids with 570 nm , for 1° and 2° with 500 nm. The system can be upgraded to a dual wavelength photometer with 440 nm and 570 nm by replacing the already installed photometer.
ARACUS CONSUMABLES
ARACUS CLASSIC, ADVANCED and LITE are supported with pre-made reagents, columns and standards for the various separations capable of performance on the three instrument configurations. Our reagents assure sample to sample, batch to batch performance of the highest quality. Time-savings is a huge plus with our reagent and standard kits.
