The results of calculations are presented that address the effect of the scan rate on peak shape and position for slow‐scan‐irate detection in the quedrupole ion trap. The calculations are based on a model for signal detection that account for the change in the number of ions in the trap as the ejection field sweeps across a peak. The calculations predict that reduced scan rates lead to peak narrowing, peak asymmetry, and a shift in the apparent mass in the in resulting mass spectrum.
