Analysis of Highly Polar Pesticides
Micro-SPE (μSPE) emerged as an automated green micromethod for sample preparation and clean-up in food safety, proteomics, forensic, environmental and analysis since more than ten years. Applications are wideranging and cover drugs, environmental contaminants, and, in particular, the extract clean-up in multiresidue pesticide analysis. The automation of the μSPE sample preparation steps led to the desired standardization of the applied sorbent materials for extract clean-up for the large variety of food commodities, an increase in sample throughput, and the welcome potential for offline and online hyphenation with GC-MS, LC-MS or even IC analysis.
Automated Mini‑Column Solid‑Phase Extraction Cleanup for High‑Throughput Analysis of Chemical Contaminants in Foods
This study demonstrated the application of an automated high-throughput mini-SPE cleanup for the analysis of pesticides and environmental contaminants in QuEChERS extracts of foods.

Automated μSPE cleanup for GC-MS or LC-MS analysis of pesticides and environmental contaminants in QuEChERS extracts of foods
Automated Clean-up of PAH in Sunflower Oil for GC-MS
The objective was to establish an automated µSPE clean-up procedure for PAH analysis in edible oils, here used sunflower oil. We were using the greater concepts of Green Analytical Chemistry and automation.
Automated Clean-up of QuEChERS Extracts for GC-MS and LC-MS
A fully automated, true green analytical method, for high sensitivity and precision pesticide analysis. This report describes for the first time a fully automated QuEChERS extraction and clean-up workflow for homogeneous matrices like fruit juices, demonstrated for orange juice.
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.

Automated Sample Preparation for pesticides using QuEChERS extraction and cleanup
The QuEChERS analysis method is a popular solid-phase extraction method used for the analysis of pesticide residues in food. However, there are analytical and logistical limitations during cleanup. The Webinar shows two workflow variations for high sample throughput in online GC-MS and LC-MS analysis.

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.
