Recent Developments of the µSPE Clean-up Workflow in Pesticides Analysis

Microextraction techniques in sample preparation have emerged as alternatives to traditional extraction techniques. Classical standard methods can be successfully scaled down to miniaturized methods. With the scale-down to only microliter volumes successful automation of these established methods is the next logical step. In contrast to only automate a former manual procedure, for instance by using the classical large volume SPE cartridges and replacing the manual steps, for a true green analytical chemistry, a new µSPE cartridge was introduced for automated processing of raw extracts for online (or offline) pesticides analysis by GC-MS or LC-MS. The use of the automated µSPE clean-up workflow shows its versatility for pesticides analysis in extractions with acetonitrile (ACN) or ethylacetate (EtOAc). Recent developments showed the feasibility also of the automated extraction process for homogeneous samples. The application of the complete QuEChERS extraction, clean-up and GC-MS injection is demonstrated for orange juice.
