Course 4 (Only in English)

13:30 - 17:30

Efficient Start-to-Finish Analysis of Pesticide Residues in Foods

Introduction and Background: purposes for analysis, data quality objectives, and validation

Sample Processing: theory and practice to quickly obtain minimal but representative sample test portions for analysis

Sample Preparation: theory and practice of different extraction and cleanup methods, including automation, to achieve high and consistent recoveries of a wide scope of analytes (or narrow scope depending on the application) while minimizing direct and indirect interferences and matrix effects from sample components

Analysis: high-throughput methods less than 10 min each in gas and liquid chromatography coupled to modern mass spectrometric techniques for the detection of hundreds of analytes in complex matrices

Data handling: how to automatically integrate chromatographic peaks with reliable quantification and identification of analytes at trace levels in complex matrices without human review or manual re-integrations

Speaker: Dr. Steven Lehotay

(United States Department of Agriculture (USDA), USA)

Research chemist (chief scientist) at the Agricultural Research Service (ARS) for the US Department of Agriculture (USDA)

Since 1992 has been researching the development and improvement of methods that analyze pesticides, veterinary drugs and other contaminants in food and environmental samples. Research addresses all aspects of the analytical process, including sample processing, preparation, separations, detection, sorting, quantification, identification/confirmation and data processing using many types of analytical techniques applied in new and useful ways

Received over 15 international awards

Author/co-author of more than 145 scientific publications and more than 220 scientific abstracts
