ARACUS “lite” Amino Acid Analyzer

The ARACUS „lite“ Amino Acid Analyzer is a simplified configuration of the ARACUS „classic“ and 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 device and the rack . The „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 equipped with manual injection mode can be connect also with an autosampler like all our devices. The „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 and 570 nm by replacing the already installed photometer.
