The chromatographic column is mainly based on the effective ingredients of plants, chemical intermediates, compounds, and other substances to be separated, as well as the different fillers inside the chromatographic column:

1. At different affinities;

2. Under different concentrations of acid and alkali solutions;

3. Under different polar solutions;

4. Under a certain pressure and at different flow rates on the filling material, different levels or components are separated in a hierarchical manner to obtain the planned effective components or components.

Bona column is suitable for molecular sieve, ion exchange, gel permeation and affinity chromatography. Advanced design, simple column installation, small "dead volume" for elution, and good chemical corrosion resistance make it a suitable chromatographic tool for laboratory and chemical pharmaceutical pilot and large-scale production in biochemistry, petrochemical, chemical analysis, disease diagnosis, and other fields.
