New Preparation Approach for Improved Pesticide Analysis of Challenging Samples

Presented by

Dr. Frank Michel, Analytical & Chromatography Scientific Advisor, Merck KGaA, Darmstadt, Germany

About this talk

For Pesticide Analysis in food and feed QuEChERS is an established Sample Preparation technique. Nonetheless there are some challenging sample matrices that require variations of the classical QuEChERS methodology. These are fat-rich matrices, intensively coloured matrices and dry, complex matrices such as teas, spices or herbs. As even the variations in the official methods AOAC 2007.01 and EN 15662:2008 cannot fully remove all matrix interferences, this talk will introduce new sample preparation approaches leading to improved clean-up and recovery of pesticides in these challenging matrices.
