Representative product ion MS analyses of lithiated DMG-DAG species. Product-ion analyses of 1,2-di16:0 (A), 1-16:0-2-18:1 DAG (B), 1,3-di16:0 (C), and 1-16:0-3-18:0 (D) DMG-DAG species were performed after selection of the corresponding molecular ions by Q1, collision activation in Q2 with collision energy of 35 eV and collision gas pressure of 1.0 mTorr, and product-ion detection by Q3. The majority of the fragment ions in the spectra were assigned.
