Analysis of dihydronaringin chalcone and naringin chalcone by UPLC-Q-IMS-TOFMS. A) Selected ion UPLC-MS chromatogram of dihydronaringin chalcone ion ([M-H]-m/z = 581.2138; calculated = 581.1870, -46.11 ppm error) with MS/MS spectrum inset. B) Ion mobility spectrum of dihydronaringin chalcone ion ([M-H]-). C) Selected ion UPLC-MS chromatogram of naringin chalcone ion ([M-H]-m/z = 579.1907; calculated = 579.1714, -33.32 ppm error) with MS/MS spectrum inset. D) Ion mobility spectrum of naringin chalcone ion ([M-H]-). E) 2-D plot of drift time vs. m/z for combined mixture of dihydronaringin chalcone and naringin chalcone. 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.
