Direct Injection of Orange Juice for the Rapid Detection of the Fungicide Carbendazim Using ACQUITY UPLC I-Class with Xevo TQ-S
Recent news about the presence of the fungicide carbendazim in orange juice (OJ) products has drawn widespread public attention on the safety of the fruit juice. In this technology brief, we describe a simple dilute-and-shoot method for the detection of carbendazim residues in orange juice at concentrations below 10 parts per billion (ppb). The ultra-high sensitivity of Xevo TQ-S Mass Spectrometer coupled with the ACQUITY UPLC I-Class System allows direct analysis of trace amounts of carbendazim in orange juice samples. The elimination of sample preparation not only results in high analysis throughput, but also simplifies the method development and optimization process, which is especially valuable to those who need to address versatile analytical requests in a short period of time.
