Separation of technical waxes by temperature-programmed packed-capillary liquid chromatography

Paal Molander, +2 more
- 01 Mar 2000 - 
TL;DR: In this article, a highmelting saturated hydrocarbon wax in the carbon range C28 to C90, with an average molecular mass of 785, and a saponified, oxidized Fisher-Tropsch wax of average molecular masses 745 have been characterized by reversed-phase packed-capillary liquid chromatography with isocratic nonaqueous mobile phases.
Journal ArticleDOI

The impact of column inner diameter on chromatographic performance in temperature gradient liquid chromatography.

Paal Molander, +5 more
- 06 Nov 2003 - 
TL;DR: The study revealed that the column ID is not a critical limiting factor when performing temperature programming in LC, at least for columns narrower than 4.6 mm, making the capillary columns generally more functional towards temperature gradients than the larger bore columns with respect to chromatographic efficiency.
Journal ArticleDOI

Separation and purification of organotin halides

Emil B. Jessen, +2 more
- 11 Jan 1979 - 
TL;DR: A satisfactory separation of the methylated tin halides and their purification from tin tetrachloride have been achieved by adsorption chromatography on Styragels as mentioned in this paper.
Journal ArticleDOI

Quantitation of High Boiling Fractions of North Sea Oil after Class Separation and Gel Permeation Chromatography

Elsa Lundanes, +1 more
- 01 Jan 1985 - 
TL;DR: In this paper, a two-column system (silica and cyano-bonded silica) with column switching and backflushing was used to separate deasphalted high boiling petroleum fractions into saturates, aromatics and polars.
Journal ArticleDOI

Determination of prostaglandins in human seminal fluid by solid-phase extraction, pyridinium dichromate derivatization and high-performance liquid chromatography.

Jo Doehl, +1 more
- 01 Jan 1990 - 
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.
