Waters Corporation has introduced the Waters Xevo quadrupole time-of-flight (QTof) mass spectrometer (MS), an exact mass MS/MS benchtop instrument which Waters claims is the most sensitive benchtop QTof system ever. Aimed at transforming every stage of the analytical laboratory workflow, Xevo mass spectrometers are designed around the philosophy of Engineered Simplicity, which combines instrument performance with simplicity of operation to enable scientists to convert data into business-critical knowledge faster and with greater assurance.

Paired with Waters ACQUITY UltraPerformance Liquid Chromatography (UPLC), the Xevo QTof MS is the only commercially-available MS system to give scientists UPLC/MSE performance — a novel method of data acquisition that captures "all of the data all of the time" at unparalleled speeds to maximize the amount of information collected from minimal sample amounts.
