One particularly important application of chromatography has been to the analysis of pesticides, their degradation and movement. Small amounts of pesticides can be determined and their interaction with soil can be modeled using chromatographic methods [30], It is unlikely that all types of chromatographic separation have been developed or even conceived. New variants such as ultrahigh-pressure liquid and hydrolitic interaction liquid chromatography are but two examples.
