High-performance liquid chromatography is an effective type of column chromatography which is widely used in pharmaceuticals. It is very useful to determine the assay and related substances in drug substances. In general, HPLC is used to separate the components of a mixed drug substance Most of the applications in HPLC require the evaluation of drugs, biochemical molecules and other substances used by humans and they are polar (water soluble) in nature. So, reverse phase HPLC is widely used. Based on principle of separation Here the HPLC is categorized based on the principle used in separation High performance liquid chromatography or commonly known as HPLC is an analytical technique used to separate, identify or quantify each component in a mixture. The mixture is separated using the basic principle of column chromatography and then identified and quantified by spectroscopy HPLC experiment, but rather the objective of the separa-tion. The objective of an analytical HPLC run is the quali-tative and quantitative determination of a compound. For a preparative HPLC run it is the isolation and purification of a valuable product (table 1). Since preparative HPLC is a rather expensive technique, compared to traditiona Introduction to the theory of HPLC Basic principles of HPLC 175 The net retention time ( or ) is the difference be-tween total retention time and dead time.
