Analysis of dihydrocinnamate and trans -cinnamate by UPLC-Q-IMS-TOFMS. A) Selected ion UPLC-MS chromatogram of dihydrocinnamate ion ([M-H]-m/z = 149.0608; calculated = 149.0602, -4.03 ppm error) with MS/MS spectrum inset. B) Ion mobility spectrum of dihydrocinnamate ion ([M-H]-). C) Selected ion UPLC-MS chromatogram of t-cinnamate ion ([M-H]-m/z = 147.0452; calculated = 147.0446, -4.08 ppm error) with MS/MS spectrum inset. D) Ion mobility spectrum of t-cinnamate ion ([M-H]-). E) 2-D plot of drift time vs. m/z for combined mixture of dihydrocinnamate and t-cinnamate. Arrows indicate position of the two compounds. Image resolution was set to 1000 bins in the MS dimension to allow for ease of viewing of the ions.
