Description
Additional Information

Irregular Silica Gel Chromatographic Filling Material

Irregular silica gel chromatographic filling materials are mostly bare silica gel, representing the most traditional and cost-effective option. They are the most suitable chromatographic fillers for industrial-scale applications under normal and low pressure. Please select the specifications and parameters according to actual requirements.

vKey Indicators:

Particle Size (external morphology, particle size distribution, density, etc.);

Pore Size (intrinsic indicators such as specific surface area, pore volume).

The selection of these two parameters is most critical, as they directly impact key production factors in chromatographic applications, such as pressure, retention value, yield, purity, and efficiency.

vSelection Guide for Irregular Chromatographic Filling Materials:

1. Selection of Particle Size:

2. Selection of Pore Size:
