The IF distributions for ginsenosides Rh2 and C-K. (A) The IF distributions of the ions at m/z 459 for ginsenoside Rh2, which can be differentiated based on the IF values at 25% in the CE range of 12–64 eV. (B) The IF distributions of the ions at m/z 375 for ginsenoside C-K, which can be differentiated based on the IF values at 3.8% in the CE range of 32–80 eV. CE, collision energy; IF, intensity fraction.
