High-pressured liquid chromatography of carotenoids

Journal of Chromatography A, 1978
Abstract The potential of high-pressure liquid chromatography (HPLC) for separation of carotenoids on silica has been studied with selected model carotenoids (carotenes, diols, cis—trans isomers and diastereoisomers) in comparison with conventional thin-layer chromatography and circular paper techniques.

Liquid-liquid partition coefficients by high-pressure liquid chromatography

Journal of Medicinal Chemistry, 1975
Lipid-water partition values can be rapidly and reliably measured by high-pressure liquid chromatography (HPLC) on bonded octadecylsialne supports. This method has been developed and applied to a family of hypotensive triaminopyrimidine 3-oxides. The measured column retention values for this class of compounds correlate well with the values calculated ...

High Pressure Liquid Chromatography of Anthocyanins

Canadian Institute of Food Science and Technology Journal, 1975
Abstract An investigation of several high pressure liquid chromatographic (hplc) systems, potentially useful in rapidly separating mixtures of anthocyanins, indicated that a polyamide material called Pellidon performed the best. Three monoglucosides of malvidin, petunidin and peonidin were successfully separated in less than 20 minutes on a ⅛″ × 4 ...

High-pressure liquid chromatography of carbohydrates

Journal of Chromatography A, 1974
Abstract A procedure is described for the separation of water-soluble wood polysaccharides on Bio-Glas (granular porous glass) and Bio-Gel P (polyacrylamide) packed columns using high-pressure liquid chromatography (HPLC). An example of HPLC employing non-aqueous solvent systems and EM Gel OR-PVA (vinyl acetate copolymer) type packing materials is ...

Forensic aspects of high-pressure liquid chromatography

Journal of Chromatography A, 1976
This paper reviews the applications of high-pressure liquid chromatography (HPLC) to forensic problems, and discusses some of the developments that have taken place in the use of the technique in the Metropolitan Police Laboratory. Preparation of octadecyltrichlorosilane-modified silica is described and some of the chromatographic characteristics of ...

Trends in High Pressure Liquid Chromatography

Berichte der Bunsengesellschaft für physikalische Chemie, 1973
AbstractThe recent developments of high pressure liquid chromatography are reviewed with the emphasis on the main problems with which the users of this technic are faced: the design of more sensitive, specific detectors, the design of systems to prepare reproducible solvent gradients and to detect small concentrations of compounds in a variable ...

Chapter 15 High-pressure liquid chromatography

2006
Publisher Summary The phenomenal growth in chromatography is largely because of the introduction of the technique called “high-pressure liquid chromatography,” which is frequently called “high-performance liquid chromatography” (HPLC). It allows separations of a large variety of compounds by offering some major improvements over the classic column ...
