Abstract
The work presented in this thesis involves the
application of mass spectrometry to the analysis of a
number of both commercial products and model organic
compounds. Use of soft ionisation techniques for
thermally labile and ionic compounds (mainly fast atom
bombardment, field desorption and thermospray) has been
extensively explored for the provision of both
qualitative and quantitative information. More
established ionisation techniques (electron impact and
chemical ionisation) have also been utilized in order to
obtain qualitative data. In many cases comparisons have
been made between different ionisation modes, and some
discussion of the processes occuring is given. Ion
structures and decomposition pathways have been
elucidated by both tandem mass spectrometry and high mass
resolution measurements.
Analysis of both complex mixtures and pure
compounds has been performed. The systems studied were:
surfactants (anionic - sodium alcohol ether sulphates,
nonionic - alcohol ethoxylates, cationics - mainly
quaternary ammonium salts), organotin PVC heat
stabilisers and organic heterocyclic compounds (some
chromans, chromenes and corresponding oximes).
