Binary High Pressure Gradient System for HPLC High Performance
Liquid Chromatography System
Introduction of Liquid Chromatography Instrument
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 degas-unit and two pumps to pass a solvent referred to
as a “ mobile phase” (e.g. water, acetonitrile, methanol etc.) and
sample mixture through a column referred to as a “ stationary
phase” filled with a solid adsorbent material, is typically a
granular material made of solid particles (e.g. silica, polymers,
etc.). 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 the column.
