WebThe Waters Xevo G2-XS QTof enables complete screening of samples using both ACQUITY UPLC and GC separations. MS E allows the scientist to get exact mass precursor and fragment ion spectra from every detectable component in the sample, simplifying the identification of components. WebIn my experience a QTOF makes a good quantitative instrument in MS mode. If you need specificity of fragment ion confirmation and potentially reduced noise you can use targeted MSMS mode to do quantitation on the product ions. However, if you just specify one precursor ion in the table the instrument will continuously switch between MS and MS/MS. cronaca napoli todayWebA triple quadrupole mass spectrometer with the final quadrupole replaced by a time-of-flight device is known as a quadrupole time-of-flight instrument. Such an instrument can be represented as QqTOF. . Ion trap time-of-flight. In an ion trap instrument, ions are trapped in a quadrupole ion trap and then injected into the TOF. The trap can be 3-D or a linear trap.. … cronaca ok

"Multiple stages of mass analysis separation can be accomplished with individual mass spectrometer elements separated in space or using a single mass spectrometer with the MS steps separated in time. For tandem mass spectrometry in space, the different elements are often noted in a shorthand, giving the type of mass selector used. " - Qtof wiki
