Waters Acquity Xevo TQ-S and Acquity UPLC I-Class

Waters Corporation has announced its analytical technique to rapidly determine residue levels of the fungicide carbendazim in orange juice with no sample preparation, at regulated levels using the Waters Xevo-TQ-S mass spectrometer and Acquity UPLC I-Class system.

The company claims the system allows users to employ a ‘dilute-and-shoot’ approach to orange juice analysis, which may increase analysis throughput and reduce method development time.

Carbendazim is used legally in Brazil and other countries for plant disease control, post-harvest food storage or transportation and seed pre-plant treatment. It is not approved for use on citrus fruit in Australia and orange juice products in Australia will not be permitted to contain any carbendazim after the first quarter of 2012.

Intensive sample preparation can be required in order to remove possible interferences and to enrich the analytes when testing for fungicides. The company claims its technique enables testing to be carried out without the need for sample preparation, which may be of benefit to users who need to rapidly meet analytical requests.
