We offer chromatography grade silica gel. Chromatography grade silica gel
column chromatography technique
in column chromatography, the stationary phase, a solid adsorbent, is placed in a vertical glass (usually) column and the mobile phase, a liquid, is added to the top and flows down through the column (by either gravity or external pressure). Column chromatography is generally used as a purification technique: it isolates desired compounds from a mixture.
The mixture to be analyzed by column chromatography is applied to the top of the column. The liquid solvent (the eluent) is passed through the column by gravity or by the application of air pressure. An equilibrium is established between the solute adsorbed on the adsorbent and the eluting solvent flowing down through the column. Because the different components in the mixture have different interactions with the stationary and mobile phases, they will be carried along with the mobile phase to varying degrees and a separation will be achieved. The individual components, or elutants, are collected as the solvent drips from the bottom of the column.
Ever since the birth of modern liquid chromatography in the late 1960’s, silica has been the media of choice for the cinematographer. No other media gives cleaner separations or bonds better than silica. No other media offers a broader range of porosity and particle size choices.
For more than 30 years, we have used our silica gel technology to provide consistent high-quality media for chromatographic separations. Ashirwad’s column chromatography grade silica gel are available in a wide variety of pore size and particle size distributions with excellent mechanical and structural properties. We offer unmatched capacity for meeting your requirements, from grams to tons. Since we are silica specialists, we also offer an unmatched ability to customize our silica media for your needs.
The mixture to be analyzed by column chromatography is applied to the top of the column. The liquid solvent (the fluent)is passed through the column by gravity or by the application of air pressure. An equilibrium is established between the solute adsorbed on the adsorbent and the eluting solvent flowing down through the column. Because the different components in the mixture have different interactions with the stationary and mobile phases, they will be carried along with the mobile phase to varying degrees and a separation will be achieved. The individual components, or pollutants, are collected as the solvent drips from the bottom of the column.
Particle size : we offer various particle size ranges as below:
in mesh size : 30-60, 60-120, 120-200, 200-400, 60-130, 130-200, 130-230, 130-400, 230-400 mesh.
Packing: 25, 40, 50 kg in cardboard barrel or iron or in h.d.p.e. Drum.
