Introduction of HPLC Liquid Chromatography Instrument:
High-performance liquid chromatography (HPLC) is a powerful analytical technique that separates, identifies and quantifies components in a liquid mixture. Compounds introduced into a solvent pass steadily through a column, and separate within the column as they pass through the packing materials and exit into a detector. The detector tracks and identifies the elements as they exit the column, and a chromatogram chart provides a visual analysis of the compounds.
