5. Waters Micromass Q-TOF
The Micromass Q-Tof hybrid quadrupole/orthogonal time of flight is a high resolution oa-Tof mass spectrometer that enables automated exact mass measurements in an easy-to-use instrument. The instrument also features a quadrupole mass filter and collision cell for MS/MS analyses. This powerful combination delivers simple exact mass measurement of fragment ions to yield increased confidence in structural elucidation and databank search results.
Regulation of source pressure and cone voltages allows tuning desolvation and in-source fragmentation. The first quadrupole can be used as an ion guide (RF only) in MS mode, or as a precursor mass selector for MS/MS.
The ions are collided with argon in the collision hexapole, and the products are analyzed in the time-of-flight (TOF) analyzer. Resolution: ca. 7,000: accuracy: ca. 5 ppm
