(a) Plot of corrected empiric cross-sections versus effective drift times for 14 peptides and 4 phosphatidylcholines (PC). For each peptide and PC the singly charged cation is used. Linear trend and power trend lines are shown as solid and dash lines, respectively. (b) A plot of the estimated cross sections versus the ion mass for PC cations investigated in this study. The estimated collision cross sections from linear trend and power trend are shown as solid squares and empty circles, respectively.
