This application demonstrated the disruptive nature of the ACQUITY UPLC System with 2D-LC Technology with the Xevo TQD Mass Spectrometer. The application targeted the analysis of microcystin RR, LR, and YR in bottled, tap, and surface water. The limit of detection in this study was 50 ppt with a 10:1 enrichment from the extraction protocol (15 min total) and a 200:1 enrichment from the at-column dilution option, for a total of 2000:1. The recovery data for bottled, tap, and surface water samples using a microextraction protocol shows comparable results to applications with macroextraction protocols.
