QuEChERS Sample Preparation for LC/MS and LC/UV Determination of Carbendazin and Other Conazole Fungicides in Orange Juice

This application note discusses the sample preparation strategies for determination of conazole fungicides, including carbendazim, in orange juice. It is demonstrated that the DisQuE pouch (QuEChERS) from Waters is effective for extraction of conazole fungicides. The methodology described here provides high-throughput and low detection limits with a quick, simple, robust, and safe analysis. It is also shown that the QuEChERS extract can be readily utilized for UPLC/MS/MS analysis without further cleanup.
