Abstract
Gas
chromatography (GC) provides the greatest revelation of the complexity
of volatile compounds, and it is little surprise that the discovery of
Partition Chromatography (including GC) was awarded Nobel prize – albeit
many years ago. This can be in as diverse areas as petroleum analysis
(Earth), atmospheric particulates (Wind), combustion products (Fire),
and environmental analysis (Water).
In AJP
Martin’s Nobel lecture, he mentioned the role of ‘two-dimensional
separations’, (i.e. TLC). Today, in the gas phase, we have made a number
of contributions to the study of complex samples by using our own
versions of multi-dimensionality in GC (MDGC), largely based on our
development of a new ‘moving’ cryogenic modulation interface. Perhaps
this can be called HOT and COLD GC. Collectively, these
allow us to bring molecular discovery of volatile compounds into our
hands. We will show how Resolution, Discovery and Endeavour are
intimately linked with Captain Cook’s journey to Australia in the
1700s.
GC is very
much an experimental science, so this presentation will largely focus on
the practical outcomes – the HOW, and WHY of our research – though we
will still plot our course through various fundamental studies. We will
exemplify the work we have recently done in Earth, Wind, Fire and Water
applications, which demonstrate our voyage of discovery afforded by
advanced GC analysis. This will include aspects of absolute chemical
analysis through application of spectroscopy in a high resolution
preparative capillary multidimensional GC mode, which has been applied
to exquisite isolation of single compounds from mixtures, followed by
NMR analysis, and in some instances X-ray crystal analysis of catalysis
products. This platform technology should offer interesting
opportunities for difficult characterisation problems.
