Characterization of the New PAL Micro-SPE Cartridge for Pesticides Extract Clean-up

Since more than ten years micro-SPE (µSPE) emerged as a micromethod for sample preparation and clean-up in food safety, proteomics, forensic, environmental and analysis. Applications are wide-ranging and cover drugs, environmental contaminants, and, in particular, the QuEChERS extract cleanup in multiresidue pesticide analysis. The automation of the µSPE sample preparation steps led to the desired increase in sample throughput, unification of the used sorbent materials for food commodities, and the potential for the online hyphenation with GC-MS and LC-MS instrumentation.

Advantages of automated and miniaturized µ-SPE clean-up in pesticides residues analysis

Recent developments in pesticides analysis extend the well-established methods to higher productivity and reliability while minimizing consumption and exposition to harmful chemicals. A workflow was developed that allows automatic preparation of calibration standards, automatic sample dilution, and automatic clean-up of sample extracts on one instrument, showing that miniaturized automated solutions are reducing errors, improving analytical consistency and protecting the environment in one convenient approach.

Walk away QuEChERS extracts clean-up

See this detailed video of the µSPE workflow for the clean-up of raw pesticides extract. The µSPE cartridge is operated in scavenger mode eluting the pesticides in a clean extract. The matrix is kept on the sorbent material. The cleaned extract can be injected without waiting time online for LC-MS or GC-MS analysis. All samples are treated on the same time axis for highest reliability.
