Two bis (quaternary ammonium bromide) surfactants, hexanediyl-1,6-bis (dimethyldodecylammonium bromide) (12-6-12) and dimethylparaphenyl- a,w-bis(dimethyldodecylammonium bromide) (12-fi-12), were synthesised and their ...

ABSTRACT The present work displays capillary liquid chromatographic column switching methodology tailored for fast, sensitive and selective determination of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid ...

The present work reports capillary liquid chromatographic (LC) column switching methodology tailored for sensitive and selective determination of the four phthalic acid monoesters monoethyl phthalate (MEP), monobutyl ...

The background for this thesis was to test some of the new column materials and columns in order to find suitable column for quality control of Omnipaque and Visipaque x-ray agent products. Focus was on the columns packed ...

This study has investigated the production of poly(styrene/divinylbenzene) monolithic columns for use in micro LC for protein separations. The 180 µm I.D. x 6 cm poly(styrene/divinylbenzene) monolithic columns were tested ...

Stereokjemisk kontroll er svært viktig i organisk kjemi. Med spiraner som utgangspunkt er det forsøkt å syntetisere rigide ligander til asymmetrisk hydrogenering. Bakgrunnen for oppgaven er beskrevet i kapittel 1. I ...

There is a growing interest in the characterisation of volatile organic compounds (VOCs) in workroom air because of the potentially adverse health effects of these compounds. Volatile organic compounds have intrinsic ...
