High-back-pressure liquid chromatography

Journal of Chromatography A, 1982
Abstract The retention behaviour of solutes on various stationary phases was studied by micro-high-performance liquid chromatography using liquefied solvents as the mobile phase. An octadecylsilylated stationary phase discriminates between coplanar and non-planar aromatic hydrocarbons in the normal-phase system using isobutane as the mobile phase ...

Method transfer from high-pressure liquid chromatography to ultra-high-pressure liquid chromatography. I. A thermodynamic perspective

Journal of Chromatography A, 2014
This is the first investigation in a series that aims to enhance the scientific knowledge needed for reliable analytical method transfer between HPLC and UHPLC using the quality by design (QbD) framework. Here, we investigated the differences and similarities from a thermodynamic point of view between RP-LC separations conducted with 3.5μm (HPLC) and 1.

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 ...

Pressurized solvent reservoir for high-pressure liquid chromatography [PDF]

open access: possibleJournal of Chemical Education, 1982
A pressurized solvent reservoir for high-pressure liquid chromatography that slightly pressurizes the mobile phase before entry into the pumping system and also filters the liquid at the same time.

High Pressure Liquid Chromatography of Eicosanoids

1985
Arachidonic acid (20:4) and other polyunsaturated fatty acids can be oxygenated in many tissues by cyclooxygenase or a variety of lipoxygenases. The intermediates formed in these reactions are then converted enzymatically to a variety of other products.

Analysis of vitamin A in eggs by high pressure liquid chromatography

Food / Nahrung, 1991
AbstractA high speed liquid chromatographic method was described for the rapid determination of vitamin A in eggs. After saponification and extraction, the sample was separated on a reversed‐phase column (C18) with acetonitrile ‐ methylene‐chloride ‐ methanol as the mobile phase. Quantitative determination was accomplished by monitoring the ultraviolet

ChemInform Abstract: LIQUID‐LIQUID PARTITION COEFFICIENTS BY HIGH‐PRESSURE LIQUID CHROMATOGRAPHY

Chemischer Informationsdienst, 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 ...
