106 Multidimensional Chromatography
ACKNOWLEDGEMENTS
The author wishes to acknowledge the efforts of his various research students from
whose work some of the applications presented here have been drawn. In particular, I
have enjoyed the excellent partnership in the pioneering PhD research of Mr (now
Dr) Russell Kinghorn. In addition, the provision of a gas chromatograph by Agilent
Technologies and columns from SGE International have enabled our work to
progress.
