Resolution for the m/z 622 and 922 peaks measured at 84 m/s as a function of (A) TW amplitude using the following settings: a symmetric square wave (11110000), guard bias was set to 15 V, and rf amplitude (Vp-p) was set to 320 V. (B) Guard bias at the following settings: a symmetric square wave (11110000), TW amplitude was set to 30 V, and rf amplitude (Vp-p) was set to 320 V.
