Analysis of Residual Pesticides in Agricultural Products Using Nexera UC Off-Line SFE-GC/MS System

Since enforcement of the positive list system for residual pesticides in foods in 2006 in Japan, over 800 pesticides have been included in the system. Consequently, there is now a strong demand for effective analytical methods encompassing any sample pretreatment steps that are capable of inspecting large numbers of pesticides. Supercritical fluid extraction (SFE) that uses supercritical carbon dioxide as the extraction solvent provides good extraction efficiency.Here we introduce an example GC/MS analysis of pesticides extracted from an agricultural products using the Nexera UC off-line SFE system.
