Sample Collection and Preparation The porphyrins, chlorophylls, bilins and related tetrapyrroles are vital for all living organisms. Natural and synthetic tetrapyrroles are used extensively in foods, cosmetics, biotechnology, pharmaceuticals, diagnostics and medicine. Methods for their separation and characterization therefore, have a very wide area of applications. Yet, there is a dearth of books dedicated to HPLC and HPLC/MS of tetrapyrroles. Lim addresses this problem admirably by providing practical HPLC and HPLC/MS protocols coupled with in-depth chromatographic and mass spectrometric reference data. These are invaluableMethods in chromatography ;v. 2.PorphyrinsChlorophyllTetrapyrrolesHigh performance liquid chromatographyMass spectrometryElectronic books.Porphyrins.Chlorophyll.Tetrapyrroles.High performance liquid chromatography.Mass spectrometry.547/.593Lim Chang Kee889826MiAaPQMiAaPQMiAaPQBOOK9910455867903321High-performance liquid chromatography and mass spectrometry of porphyrins, chlorophylls and bilins1987945UNINA
