Analysis of Captan, Folpet, and their Derivatives in Food with APCI-LCMS™-8060

Introduction

Captan, Folpet, and their derivatives are fungicides widely used in agriculture. In view of their toxicity and ecotoxicity, the concentration of these compounds is monitored in food. For this, a sensitive and fast method has been developed using the Shimadzu LCMS-8060 system with an APCI interface. The samples were prepared by QuEChERS and dSPE following EN 15662:2018 norm. This method allows the analysis of food extract with limits of quantification below the regulation, described in (EC) No 396/2005 or Joint FAO/WHO Meeting (https://apps.who.int/iris/bitstream/handle/10665/440 64/9789241665230_eng.pdf?sequence=1&isAllowed= y). This method ensures that good repeatability is obtained even in difficult matrix like matcha tea. This LC/MS method provides a good alternative to GC/MS methods that are considered less robust.
