Occam’s razor-based deconvolution of the subset of signals associated with the C_nH_mO₂ species as registered by the DFMS on 3 August 2015. The measured signals (ms) are given in arbitrary units (a. u.) with 50% error margins. With the color coding, we show the different contributions of the individual molecules to the observed sum fragmentation pattern of the C_nH_mO₂ species (see details in the main text). The following 27 molecules have been selected: (51) carbon dioxide, (52) formic acid, (53) glyoxal, (54) acetic acid, (55) glycolaldehyde, (56) methyl formate, (57) ethylene glycol, (58) 2-propenoic acid, (59) propanoic acid, (60) 2-methoxyethanol, (61) methylal (62) 1,2-propanediol, (63) 2(3H)-furanone, (64) cyclopropanecarboxylic acid, (65) γ-butyroīactone, (66) 1,3-dioxane, (67) 1,4-dioxane, (68) butanoic acid, (69) 1-ethoxy-1-methoxyethane, (70) diethyl peroxide, (71) 3-furaldehyde, (72) 2-furanmethanol, (73) cyclopropanecarboxylic acid methyl ester, (74) propanoic acid ethyl ester, (75) 4-methyl-1,3-dioxane, (76) hydroquinone, and (77) benzoic acid.
