Liquid chromatography is an analytical technique utilized extensively in the pharmaceutical sector. In the pharmaceutical sector, all manufactured products will need to be of the highest quality to ensure the least risk to patients. To ensure that goods pass certain criteria, researchers, producers and programmers utilize various technical gear and analytical techniques, such as liquid chromatography, during the evolution procedure. Liquid Chromatography is an analytical technique that is used to divide a specific sample into its unique components.1 The separation takes place when the sample interacts with the mobile liquid and stationary phases column. The various areas of the sample are separated out according to their polarities; they will have varying degrees of affinity for the mobile phase, leading to migration through the column at different rates.

The mixed Components are placed on peak of the column of the stationary phase, which is normally a fine adsorbent solid like silica. This has to be distributed evenly to minimise the presence of air bubbles which could influence the outcome of the test. The exit of the column is stoppered with wool, glass or a porous plate. When the mobile phase passes through, the mixture separates into groups. These can then be gathered and analysed via other methods. The method works as the Components in a mixture are drawn to the adsorbent surface of the stationary phase with varying levels depending on their personal polarity and their structural characteristics; a part with a higher affinity for the stationary phase will migrate down the pillar slower than a part which has more affinity for the mobile stage.

The most common kind of liquid Chromatography in use now is high energy liquid chromatography, which pumps the sample mix through the column at high pressure. The kind of hplc testing that is usually utilized in the pharmaceutical sector, as it can offer the exact results that are necessary. The results can be used to analyse finished drug products and their components quantitatively and qualitatively during the production procedure. This is accomplished through the separation, quantification and identification of components in a combination and may be used to show the identity of a medication and track the development of a treatment on a disorder. Although Expected initially to be utilised as a complimentary technique to gas chromatography, the pharmaceutical industry today almost exclusively uses HPLC as a chromatographic technique. One of the principal advantages of HPLC is its ability to elucidate the structure and ascertain the quantities of impurities in pharmaceutical formulations.
