chromatogram
Figure 2: LC-MS chromatogram of each GEs compound in 0.05 g of extracted oil from pork meat patties cooked by charcoal grill. For the selected ion monitoring measurement, each of the protonated molecular ions [M + H]+ were used: m/z 313.3 for C16:0-GE, m/z 341.4 for C18:0-GE, m/z 339.4 for C18:1-GE, m/z 337.4 for C18:2-GE and m/z 335.4 for C18:3-GE.
