The Waters Xevo G2-XS is a bench-top QTOF mass spectrometer, designed for the analysis of a wide range of compounds in complex and challenging samples. The instrument incorporates StepWaveTM ion-transfer optics which increase the efficiency of ion transfer and remove neutral species from the ion beam, increasing sensitivity. The instrument is equiped with an ESI LockSprayTM source to allow accurante mass analysis by direct infusion or by LC. The XS collision cell allows fast and sensitive MS/MS experiments to be performed alongisde conventional experiments. This system used for metabolomics projects. The MS can be used either with a conventional Acquity LC system or a UPC2 for supercritical fluid chromatography.
