Overview and Application

The ST-2021 Plus automatic preparation instrument adopts a modular design, utilizing a precise and flexible robotic arm and a multifunctional sample selection system. It is corrosion-resistant with multiple flow paths and uses a high flow metering pump to quickly separate various groups in the sample, reducing the single analysis time to 30 minutes. High speed improvement of sample processing efficiency.

Instrument principle

Dilute samples such as crude oil, heavy oil, residue oil, wax oil, slurry oil, lubricating oil, chromatographic fixative, and grease with diluents. Take a certain amount of diluent and add it to a specially designed separation column. Rinse with four different polarity flushing agents to obtain four different components, thus achieving sample separation.
