Analysis of Do-it-Yourself (DIY) flavourings. (A) Bottles of DIY flavourings in which nicotine was positivity identified. Bottles are indicated by inventory numbers. Numbers 53 and 69 are duplicate bottles of Sinful Cinnamon, #106 is Nilly Vanilla and #107 is Joosy Froot. (B) Table summarising the high performance liquid chromatography (HPLC), and gas chromatography and mass spectrometry (GC-MS) results. The table indicates inventory number, flavour, quantified nicotine concentration (NQ=nicotine was not quantifiable but was qualitatively determined to be present) and GC-MS confirmation of nicotine. (C and D) Three-dimensional chromatograms of HPLC analysed flavourings, x axis=time (min), y axis=absorbance (mAU), z axis=wavelength (nm). (C) an example of a DIY flavour without nicotine (#119 Mr Bubble) and (D) an example of a DIY flavour (#107 Joosy Froot) that contains nicotine, as indicated by the ultraviolet absorption spectrum present at approximately 8 min. (E and F) GC-MS analyses of flavourings. GC data are shown in the two upper graphs, x axis=time (min), y axis=abundance (mAU) and MS data are in the lower graphs, x axis=m/z, y axis=abundance (mAU). (E) The nicotine standard and (F) an example of a flavouring (#107 Joosy Froot) found to be positive for nicotine.
