Silica Gel Column Chromatography

Column chromatography is the ideal method of chromatography for purification and separation. It is a technique in which the stationary phase is solid adsorbents like silica gel and activated alumina powder and the mobile phase is a liquid. The principle of active compound separation depends on the activity of adsorbents and polarity of the solvent. If the polarity of the solvent is very low ...
