Abstract

The advances in chemical and flavour knowledge that can be made through improved separation and identification capabilities cannot be underestimated. In this paper, we explore a number of new integrated methods that we have recently introduced that permit improved resolution and separation power for a range of analytical studies. These focus on multidimensional gas chromatography, comprehensive two-dimensional gas chromatography (GC), olfactometry, mass spectrometry and nuclear magnetic resonance spectroscopy. The overriding aim is to provide technical solutions that employ the best possible separation of compounds. Better separation of compounds allows tools such as olfactometry, mass spectrometry, nuclear magnetic resonance spectroscopy, and other detectors to provide much better characterisation of separated chemical species. We demonstrate various novel strategies that provide the necessary separation power, integrated with specific detection steps. Case studies in the areas such as sensorydirected identification of a woody odorant in hop essential oil, correlation of compound identifications in coriander leaf, and development of new preparative capabilities in multidimensional GC with nuclear magnetic resonance spectroscopy.
