How does HPLC (high performance liquid chromatography) work?

WebHigh Performance Liquid Chromatography (HPLC) is an analytical technique used to identify the components in a mixture and separate mixtures of very similar compounds. What is HPLC? HPLC can be used to separate the constituents of a compound, tell you how much of each compound is found within the mixture and helps to identify what each compound is. WebMar 17, 2024 · High performance liquid chromatography (HPLC), as the name would suggest, is the high-performance variant used for high efficiency separations with high chromatographic resolution.

HPLC is used to quantify, identify and isolate the components of non-volatile liquid mixtures (volatile compounds are separated by GC- Gas Chromatography). Solvent is pumped from a solvent reservoir and mixed with the liquid sample.

WebAbstract Reversed-phase high-performance liquid chromatography (RP-HPLC) involves the separation of molecules on the basis of hydrophobicity. The separation depends on the hydrophobic binding of the solute molecule from the mobile phase to the immobilized hydrophobic ligands attached to the stationary phase, i.e., the sorbent.
