Fig. 4From: Enhanced differentiation of isomeric RNA modifications by reducing the size of ions in ion mobility mass spectrometric measurementsMS/MS spectrum of m6A in the trap cell under the standard MS/MS method or m6a in the transfer cell under the SRI method. The CID energy used in the trap and transfer cell was 80 V and 160 V, respectively. The ion counts for 107.9529 m/z ion in both cases reached 2e+4 and 5e+4, respectivelyBack to article page
