a Extracted ion mobility spectra of nucleobases that resulted from using the SRI method. b MS/MS spectrum of m3C in the trap cell under the standard MS/MS method or m3c in the transfer cell under the SRI method. The CID energy used in the trap and transfer cell was 80 V and 140 V, respectively. The ion counts for 108.9492 m/z ion in both cases reached 5e+4 and 4e+4, respectively. m3c, 3-methylcytosine; m5c, 5-methylcytosine; m3C, 3-methylcytidine
