HPLC is a very common method for metabolomics analysis. With the invention of electrospray ionization, HPLC is coupled to mass spectroscopy. HPLC has lower chromatographic resolution, requires no derivation for polar molecules and separates molecules in the liquid phase. Relevant to proteomics, due to the complex structure and nature of proteins, instrumentation and methods development for sample clean-up, pre-concentration, fractionation, chromatographic separation and detection becomes an immediate requirement for the identification of peptides and proteins. Latest techniques and equipment for separation and detection include nano-HPLC and multidimensional HPLC for protein and peptide separation. HPLC is considered as most reliable and most sensitive technique in genomics used to determine DNA methylation. HPLC finds applications in glycomics and lipidomics. In case of glycolipids, they can be analysed directly without separation of the lipid component. HPLC has a wide application in lipidomics to separate lipids prior to mass spectrometry. Separation can be achieved by either reverse-phase (RP) HPLC or normal-phase (NP) HPLC.
