The application of capillary electrophoresis and liquid chromatography/mass spectrometry to the analysis of anaerobic and cyanoacrylate adhesives

Abstract

This thesis details the application of separation techniques to the analysis of anaerobic and cyanoacrylate adhesives Chapter 1 is an introduction to adhesives, where the chemistry, composition and analysis of both types of adhesives are discussed. Chapter 2 represents the analytical study into the determination of the products of decomposition of two reducing agents in anaerobic adhesives. The decomposition of the reducing agents, 1,2,3,4 tetrahydroquinohne and dihydropyndine, in the presence of saccharin, maleic acid, cumene hydroperoxide and the metals, iron and copper, was investigated utilising Liquid Chromatography/Mass Spectrometry. A system was developed which was applied to the LC/MS determination of the products. This chapter also includes a brief discussion on LC/MS and the cure chemistry of the cyanoacrylate adhesives. In Chapter 3 the application of Capillary Electrophoresis to the separation of basic components found in cyanoacrylate adhesives is detailed. This chapter includes a literature survey on the analysis of basic compounds with Capillary Electrophoresis. An investigation into the optimum system for the separation of piperidine, dipipendinomethane and ethylpipendme carboxylate was carried out. The study includes an assessment of the suitability of a variety of electrolytes for the separation. In Chapter 4 suggestions for future research are made and conclusions are drawn from the work carried out in the thesis
