Fig. 2From: An in silico MS/MS library for automatic annotation of novel FAHFA lipidsExperimental and in silico MS/MS spectra of one standard for validation 12-OAHSA in negative ionization mode. Spectra were acquired at a collision energy of 20 V at 4 spectra/s and b collision energy of 40 V at 1 spectrum/s. The actual relative intensities for m/z 113 and 169 are 0.2 and 0.1 %, respectivelyBack to article page
