Chromatography for Chemical Separation: Types and Uses
Abstract: Chromatography is an analytical tool that is used for separating a variety of chemical mixtures. This technique was developed somewhere during the 1940s to 1950s. Initially, the technique had low efficiency with prolonged time of analysis and reduced detection range. Later, the technique was modified and improved to meet the demands of chemical separation technology. Chromatography is broadly categorized into analytical or preparative. Analytical chromatography is used for small sample …
