overview
In recent years, because of its advantages of high efficiency and easy operation, supercritical fluid chromatography (SFC) continues to develop. SFC uses supercritical fluid as the main mobile phase.
The advantages of using carbon dioxide as a carrier are huge, reducing the use of expensive and harmful organic solvents. With SFC, solute diffusion is faster than with traditional HPLC techniques.
ASATM's patented axial SFC column hardware system is based on the concept of axial compression loading, but is designed to withstand high pressures.

1. Protective column set
ASA protective column set can effectively reduce the pollution of the filling in the SSC column, thus increasing the life of the prepared column, reducing the reinstallation frequency of the column, and improving the efficiency. The protection column adopts the patented minimalist design mode and extracts the essence of SSC design, which not only realizes the function of preventing column pollution, but also eliminates the problem that other protection columns are easy to collapse and do not support reinstallation. The reinstallation process is very simple and can be completed in about 10 minutes.
