High Performance Liquid Chromatography(HPLC)

Our high-performance liquid chromatography (HPLC) is a powerful analytical technique used in chemistry and biochemistry to separate, identify, and quantify components within a liquid mixture. It operates by passing a liquid sample through a column packed with a stationary phase, which interacts with the sample's components based on their chemical properties. A pump delivers the sample into the column, while detectors, such as UV-Vis or fluorescence detectors, monitor the eluent as it exits the column. The resulting data generates chromatograms, providing information about the individual components' retention times, concentrations, and molecular characteristics. HPLC is valued for its high resolution, sensitivity, and versatility, making it an essential tool in pharmaceuticals, environmental analysis, food science, and biochemistry. It's used for tasks like drug purity testing, amino acid sequencing, and analyzing complex mixtures in fields ranging from quality control to scientific research, enabling precise and reliable analysis of diverse compounds and molecules in a wide array of applications.
