(a) PEPICO map of the effluent stream of DME conversion over ZSM-5 zeolite at 375°C ionized using light with 40 eV energy, (b) integrated binding energy spectrum and (c) integrated ion TOF spectrum with false coincidences subtracted. For higher TOF, the spectrum intensity is multiplied by 15 to make it more clear. The corresponding mass per charge ratios are mentioned for groups of TOF peaks. |
