WebAs the mobility of the ions during the two parts of the waveform is rarely equal, there is usually a net drift towards one of the electrodes. In FAIMS, this net drift is corrected for by applying an additional DC voltage, known … WebWith high resolution ion mobility separation, timsTOF adds an orthogonal dimension that increases peak capacity beyond the resolving power achieved by chromatography and time-of-flight. Whereas unresolved precursor ions can yield inconclusive structural assignment, timsTOF enables more confident and specific identification.
