Analysis of phloretin (dihydronaringenin chalcone) and naringenin chalcone by UPLC-Q-IMS-TOFMS. A) Selected ion UPLC-MS chromatogram of phloretin ion ([M-H]-m/z = 273.0876; calculated = 273.0763, -41.38 ppm error) with MS/MS spectrum inset. B) Ion mobility spectrum of phloretin ion ([M-H]-). C) Selected ion UPLC-MS chromatogram of naringenin chalcone ion ([M-H]-m/z = 271.0612; calculated = 271.0607, 1.84 ppm error) with MS/MS spectrum inset. D) Ion mobility spectrum of naringenin chalcone ion ([M-H]-). E) 2-D plot of drift time vs. m/z for combined mixture of phloretin and naringenin 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.
