Journal ArticleDOI
Supercritical fluid chromatographic separation of low- to medium-polarity compounds that are difficult to elute from packed columns
TL;DR: In this article, supercritical fluid chromatography with flame ionization detection of unsubstituted and substituted heavy carboxylic acids (C18-C30) and various polymer additives (PAs) is demonstrated.
Journal ArticleDOI
Techniques and applications in supercritical fluid chromatography
TL;DR: In this article, the authors give a realistic view of the present possibilities by discussing three limitations of supercritical fluid chromatography (SFC): solubility, particularly of polar solutes, in various fluids.
Journal ArticleDOI
Determination of prostaglandins in human seminal fluid by solid-phase extraction, pyridinium dichromate derivatization and high-performance liquid chromatography.
Jo Doehl,Tyge Greibrokk +1 more
TL;DR: The stability of dilute standard solutions of PGE2 and PGD2 was measured, showing solutions in dichloromethane at 20 degrees C to be as stable as acetonitrile solutions at 5 degrees C over a period of thirty days.
Journal ArticleDOI
Mobile phase deliver in supercriticalfluid chromatography
TL;DR: In this article, the properties of two syringe pumps and two reciprocating piston pumps in supercritical-fluid chromatography (SFC) have been compared and it was found that the piston pumps were not compatible with CO2 as the mobile phase, due to leaks at the piston seal.
Journal ArticleDOI
High-performance liquid chromatographic separation and determination of prostaglandins, oxidized by pyridinium dichromate : Optimization and applications
Jo Doehl,Tyge Greibrokk +1 more
TL;DR: In this paper, an optimization of a previously reported one-step UV derivatization procedure in which prostaglandins are oxidized to their corresponding 15-oxo derivatives with pyridinium dichromate in acetonitrile was presented.
