Flash Chromatography And Flash Columns
Invented by Professor Clark Still of Columbia University several years ago, flash chromatography was popularized nowadays. To replace the slow and inefficient gravity-fed chromatography, flash chromatography works differently from the old ways.
Slightly smaller silica gel particles are used, and the pressurized gas is used to drive the solvent through the column of stationary phase because the restricted solvent flow is caused by the small gel particles in practice. Due to these two innovation, we can get a high efficient resolution chromatography.
You can always find Hawach flash columns with special high purity stationary phased packed with the full range of sizes. With the cartridge made from medical grade virgin PP material and PE frits.
From hydrophilic to hydrophobic, Hawach offers excellent separation performance flash columns for compounds analysis of a varies of properties. And the stationary phase includes Standard Silica gel, Superior Silica gel, Spherical C18, Irregular C18, Spherical NH2, Spherical C4, Spherical C8, Spherical CN, Spherical HILIC, Neutral Alumina, Spherical Phenyl, Spherical SAX, Spherical SCX, Spherical C8, Spherical Diol, etc..
