NH2 Flash Column

Description of Spherical NH2 Flash Column

Spherical NH2 Flash Column has good retention for compounds which be capable of forming hydrogen bonds. The mobile phase water content with a slight effect on the flash chromatography reaction and ideally separation efficiency can be guaranteed.

Advantages of NH2 Flash Column

• ISO9001 approval, COA, and MSDS are available for each batch;
• The wide range of pore size and particle size for the wide application;
• Cartridge with easy connection to most of the instrument systems;
• Clean column and clean packing and excellent column pressure;
• Cartridge with a maximum operating pressure of up to 200 psi;
• Superior high-purity silica sorbent ensures excellent separation inefficiency.

Features

• Clean column and clean packing and excellent column pressure;
• The frits for the column from 4g to 40g with the pore size of 16~20um;
• Medical PP cartridge tube makes no extractable and wide compatibility;
• The ultrapure NH2 functional group bonded silica for icon exchange flash column;
• Compatible with most of the flash instruments such as Grace, Biotage, Moritex, Armen, etc.

Applications

Ideally for the purification of compounds mixed with basic properties.

When activated with non-polar solvents such as n-hexane, it can hydrogen bond with any molecule containing -OH, -NH, or -SH groups; in a water-based environment, pH <7.8, it can be used as a weak anion exchanger. NH2 filler matrix silica gel has an average particle size of 45 μm, an average pore diameter of 60Å, a pore volume of 0.80 cm3/g, and a specific surface area of 480 m2/g.
