The Waters Xevo QTOF G2-XS mass spectrometer is a new high-performance benchtop quadrupole time-of-flight (QTof) mass spectrometer. Featuring the new XS Collision Cell, the Xevo G2-XS QTof stands alone among its peers in offering uncompromised analytical sensitivity and selectivity in a benchtop QTof mass spectrometer. The Xevo G2-XS QTof mass spectrometer combines the new XS Collision Cell with the proven, signature technologies of Tof-MRM, StepWave, and QuanTof to deliver optimum levels of robust sensitivity and selectivity, resulting in the detection of more low-level compounds than ever before. For targeted quantitative experiments, Tof-MRM mode delivers a 10-fold improvement in signal-to-noise when compared with full scan mode, resulting in limits of detection and quantification that completely redefine expectations for a benchtop high-resolution mass spectrometer.
The instrument has a new PC and a new scroll pump, manufacturing date is February 2015.
