摘要

Sample preparation is a crucial step in any analytical method, especially in chromatography where the samples have to be homogenous, free of interferences and safe for the column. Frequently, the component of interest is present in levels too low for detection. Sample preparation can concentrate the component to adequate levels for measurement. The task is often the enrichment of the component; the selectivity of such enrichment can be enhanced by using cyclodextrincontaining sorbents. Either crosslinked or immobilized CDs and derivatives can improve the recovery of certain components to be measured. Some analytical sample preparation techniques (SPE, SPME, SBSE) applying cyclodextrins are introduced here.
