Pesticides from Food Surfaces Using LESA PLUS Liquid Extraction Surface Analysis PLUS LC Separation

Residues and contaminants in the food chain are an increasing problem due to high production volumes, large area distribution and import/export of food items across the world. The novel LESAPLUS surface analysis approach combines the standard liquid extraction surface analysis with an additional step of a nano liquid chromatography separation. This combination is ideally suited to investigate residues and contaminants on surfaces of interest and allows both rapid and direct screening as well as in depth analysis of suspect food samples.
