![Electrospray ionization (negative ions) and tandem mass spectrometry of common fatty acids as their carboxylate anions. (A) Product ions obtained following collisional activation of palmitic acid (16 : 0), m/z 255; (B) product ions obtained following collisional activation of stearic acid (18 : 0) [M − H]− at m/z 383; (C) product ions obtained following collisional activation of oleic acid (18 : 1, n-9) [M − H]− at m/z 281; (D) product ions obtained following collisional activation of docosahexaenoic acid (22 : 6, n-3) [M − H]− at m/z 327.
