Three parameter thermodynamic predictive models have been shown
previously to provide superior accuracy in the prediction of gas chromatographic
retention times in comparison to other forms of modelling such as retention
indices. However, these models suffer from the need for extensive
experimentation to generate the data required to make their predictions. This then
limits the applicability of the method to real world situations. This thesis sets out
to explore new methods and techniques that reduce the required experimentation
necessary to make thermodynamic based retention time predictions in gas
chromatography. Three main ideas are explored in the process of reducing
experimentation: the automation of thermodynamic data collection, the adaptation
of thermodynamic collection models from isothermal to temperature programmed
based experimentation and a method to rapidly transfer thermodynamic data from
one chromatographic system to the next. Along with the above stated goals, this
research sets out to develop models for the prediction of retention times in two
dimensional gas chromatography using three parameter thermodynamic data. Two
dimensional separations are also used to validate the methods and concepts
mentioned previously. -
