1. Basic principles:   Liquid chromatograph is a commonly used analytical instrument, widely used in chemistry, biology, environment and other fields. The principle is based on the separation of components in the solution based on the difference in the interaction force between the stationary phase (filler) and the mobile phase (solvent). When the sample enters the chromatographic column, the sample...
