Screening of pesticides in water using SPE on line

Pesticides are widely used in agricultural products to protect crops from insect infestation during cultivation and product transport. The abuse of pesticides can cause important environmental pollution in different areas, especially at levels of lakes, rivers and aquifers. For this reason one of the most important and attractive application is the possibility to analyze pesticides in water and better if it is without pretreatment of the sample. Shimadzu in cooperation with Arpa Asti (Italy) developed a system for injection of water samples using a triple quadrupole system using a Solid-Phase Exctraction (SPE) on line. We injected water samples in a LCMS-8030 Shimadzu triple quadrupole instrument coupled Nexera UHPLC instrument in order to identify a mixture of 48 substances.
