描述

一般說明

High purity grade silica gel offers the lowest moisture content, tightest particle size distribution, minimal impurities and greatest lot-to-lot consistency which results in greater reproducibility of the separation process. It is useful for all types of low pressure, medium pressure, and flash column chromatography. They can be applied to the clean-up and purification of a wide range of synthetic and natural compounds. A spherical particle shape results in more homogenous packing characteristics, providing sharper peak adsorption and elution curve.
