Figure 4-4. Ag-HPLC/APCI-MS chromatogram of monoacid triacylglycerols standards. Numbers correspond to the double bonds number. Inset zoom shows the resolution of saturated TG from C7:0 to C22:0. Concentrations of all standards are identical except for C16:0, C18:0, and C20:0 with doubled concentrations. Ag-HPLC, silver ion high-performance liquid chromatography; APCI, atmospheric pressure chemical ionization; MS, mass spectrometry.
