Strategies for On-Line Sample Enrichment and Confirmation of Analytes in a Complex Food Matrix

Regulatory agencies have been testing orange juice for pesticide residues and adulteration for decades. in early 2015, the U.S. FDA announced it was investigating reports that low levels of the fungicide carbendazim were being detected in imported juices. Performing HPLC/UV methods as a first test for compounds was very time consuming, which led to the development of an easy mass detection method. This application note describes the use of Water's ACQUITY QDa Mass Detector to carry out this quality control method.
