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 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 ...

Parts of south-west China are heavily exposed to acid deposition. This is the cause for the IMPACTS (Integrated Monitoring Project on Acidification of Chinese Terrestrial Systems) project, to which this thesis is related. ...

In the present work, pI-separation of proteins by pH-gradient ion-exchange chromatography (IEC) on packed capillary columns is demonstrated. An important technical challenge for adapting this technique to capillary dimensions, ...

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 ...

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 ...
