Description

Remarque sur l'analyse

Simple and fast extraction and analytical method were developed for analysis of fungicide carbendazim in orange juice samples. QuEChERS extraction method was used with PSA/C18 cleanup. Ascentis Express C18 column chromatography was coupled to MS/MS detection with limits of detection at 0,1 ppb.
