High-performance liquid chromatography, or HPLC, is a highly versatile technique that separates components of a liquid mixture based on their different interactions with a stationary phase. There is only one theory of chromatography: A plug of sample flows in a mobile phase past a stationary phase. The liquid solvent containing the sample mixture passes through a column filled with a solid adsorbent material. Modern HPLC systems have been improved to work at much higher pressures, and therefore are able to use much smaller particle sizes in the columns (<2 μm). or liquid chromatography-tandem mass spectrometry2,3,4,5). sheet of paper or cloth contacts a container filled with water or alcohol in which a complex pigment is dissolved, capillary action Since its infancy in the late 1960s and early 1970s, the use of high perfor­ mance liquid chromatography (HPLC, or LC as it is increasingly becom­ ing known) has expanded rapidly.
