Analysis of Highly Polar Pesticides
Application Notes

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.

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.

Analysis of flavors, pesticides, and biomarkers directly from complex food matrix using the automated Vacuum In-Tube Extraction (V-ITEX)

Extraction of volatile compounds is a widely used approach for analysis of foods and beverages.  By the nature of gas phase sampling, the limiting factor for polar analytes are given by low vapor pressure or higher boiling points of semi-volatile compounds. These limitations can be overcome by sampling at decreased pressure levels using vacuum conditions. This has been shown in several publications using vacuum sampling techniques. In this study, a fully automated approach of Vacuum In-Tube Extraction (V-ITEX) is presented, a simple and fully automated technique using PAL system autosamplers. The application examples include flavors, fragrances, off-flavors, pesticides and biomarkers by extractions directly from the food sample matrix, such as Honey, Bee Wax, Cheese, Onions, Blood and Urine.
