High-performance liquid chromatography HPLC is a technique in analytical chemistry used to separate the components in a mixture, and to identify and quantify each component. It was initially discovered as an analytical technique in the early twentieth century and was first used to separate colored compounds. The word chromatography means color writing. It was the botanist M. He separated the pigments based on their interaction with a stationary phase.
The key focus of the pharmaceutical or chemical industries is to reduce the cost involved in the development of new drugs and to improve the selectivity, sensitivity, and resolution for their detection. The underlying principle of UPLC is based on van Deemter statement which describes the connection between linear velocity with plate height. UPLC contributes to the improvement of the three areas: speed, resolution, and sensitivity. This is a new advanced category of the HPLC which has the same basic principle and methodology with improved chromatographic performance. This review is an effort to compile the principle, instrumentation, and applications of UPLC. High-performance liquid chromatography HPLC is an important liquid chromatography LC technique used for the segregation of different components in mixtures.

The aim of this organization is to provide access not only to world class research resources, but through its professionals aim to bring in a significant transformation in the real of open access journals and online publishing. Abstract : High performance liquid chromatography HPLC is a significant qualitative and quantitative technique, usually used for the estimation of pharmaceutical and biological samples. The chromatography term is derived from the Greek words namely chroma colour and graphein to write. The chromatography is very accepted technique and it is mostly used analytically.
Chromatography is a technique to separate mixtures of substances into their components on the basis of their molecular structure and molecular composition. This involves a stationary phase a solid, or a liquid supported on a solid and a mobile phase a liquid or a gas. The mobile phase flows through the stationary phase and carries the components of the mixture with it. Sample components that display stronger interactions with the stationary phase will move more slowly through the column than components with weaker interactions. This difference in rates cause the separation of variuos components.

High-performance liquid chromatography HPLC , formerly referred to as high-pressure liquid chromatography , is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out of the column. HPLC has been used for manufacturing e.
