Advantages of automated and miniaturized µSPE 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 Preperation for LC/MS and GC/MS - Solutions for Food and Environmental Analysis
In this presentation we want to discuss an important development and a demand from analytical laboratories about the standardization and the automation of sample preparation procedures for food safety, environmental, the forensic or pharmaceutical analysis.

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.
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.
Fully Automated QuEChERS for Organochlorine and Organophosphate Pesticides in Tomato Juice and Red Wine
Using PAL Robotic Tool Change (RTC) system, a fully automated QuEChERS was developed for the extraction and clean-up of organochlorine and organophosphate pesticides from homogeneous samples. The automated QuEChERS workflow includes extraction with acetonitrile, salting out with
saturated sodium chloride solution and the clean-up with PAL μSPE prior to injection into the GC-MS/MS for analysis.
