Analysis of Captan, Folpet and Their Derivatives in Water by APCI-LCMS™-8060

Captan, folpet and their derivatives are fungicides that are widely used in agriculture. In view of their toxicity and ecotoxicity, the concentration of these compounds is also monitored in drinking water and public waters. For this, a fast, sensitive method which does not require sample preparation was developed based on the performance of a Shimadzu LCMS-8060 system with an APCI interface. This method allows the analysis of drinking water and surface water and provides a quantification limit of 30 pg/mL with good repeatability and accuracy.
