Effect of Jitter on Digital Mass Filter Analysis in Higher Stability Zones.

Waveform reproducibility is a critical factor for performing high resolution mass analysis with digitally operated quadrupole mass filters and traps operating in higher stability zones. In this work, Hill equation-based stability calculations were used to define the effect of period jitter on mass analysis in higher stability zones. These calculations correlate well with experimental observations in higher stability zones. Comparison of experiment to theory supplies the basis for defining jitter-based expectations and limits for mass analysis in higher zones.
