7Tyrannosaurus rex chromatography workstation

Tyrannosaurus rex The 1.0 chromatography workstation is customized and developed by a professional software company, and is a large-scale chromatography software work platform developed according to the structure, functions, modes, and operation methods of today's international mainstream chromatography software. Its functions are very powerful.

Unlike most domestic ion chromatography manufacturers who use multiple software simultaneously, the control and data processing of the instrument are integrated into one, and only one software is used to complete all detection functions. The data is saved in database format, which meets certification requirements.

It can display multiple detector windows simultaneously and control multiple chromatographs to run in parallel.
