Normal phase flash silica gel column chromatography has SiO4 tetrahedron structure and active hydrophilic surface. The water molecules interact with the exposed surface through hydrogen bonds to form acidic silica gel. Porous properties and silanol functional groups make silica gel an economical chromatographic separation material, which can separate weakly polar compounds, and a mobile phase with a weaker polarity is required.
Advantage of Standard Silica Gel Flash Columns
Filter packing material is of high purity to guarantee high separation efficiency.
Excellent column back pressure with higher efficiency
Column structure ensured no leakage
The polypropylene cartridge and joint to tolerate the column pressure for fast flash chromatography
PE Frits with pore size selectivity for customer use
The particle size is narrow and with a high bulk density
