2 Figure S1. Ion source and drift tube schematic.
3 Figure S2. Ion guide voltage settings. The top panel shows the absolute voltage setting (from ground); the middle panel highlights the changes in voltage potential between H3O + and NO + settings, and the bottom panel is a cartoon of the ion guide section taken from the CI-API manual (Aerodyne Inc./Tofwerk AG). The horizontal (axial) distances are not to scale.
4 Figure S3. Comparison of product ion distributions between NO + CIMS and H3O + CIMS. The complete product ion distribution of n-propylbenzene is shown as an example of a compound with a complex mass spectrum resulting from H3O + chemistry, and a simple mass spectrum resulting from NO + chemistry. Figure S4. Product ion distributions of selected aliphatic hydrocarbons, at a relative humidity of 20%.
5 Figure S5. Example chromatograms and relative sensitivity calculation of ethanol for Table 2. Figure S6. Humidity dependence of primary ions and VOCs. (a) Impurity ions and water clusters. (b) Carbonyls. (c) Aromatics. (d) Acetonitrile. Acetonitrile is detected with poor sensitivity using NO + ; the NO + and H3O + products are approximately equal in magnitude.
6 Figure S7. Speciated contributions to various NO + CIMS masses, in urban air. Values on Y-axes are the fractional contribution of each VOC to total signal. Includes m/z 41-m/z 78.
7 Figure S8. Figure S7, continued. Includes m/z 82-m/z 111.
8 Figure S9. Figure S7, continued. Includes m/z 113-m/z 144.
9 Figure S10. A. Background and ambient measurements taken during urban air sampling with the NO + ToF-CIMS. B. Example multiple-point calibrations of the NO + ToF-CIMS showing sensitivity linear with concentration.
10 Figure S11. Example isobaric interferences for heptanone measured with H3O + CIMS, at m/z 115 C7H14OH +, and with NO + CIMS, at m/z 144 C7H14ONO +. Although the resolution m/dm is better at m/z 144, there are more possible isobaric interferences and the average distance to neighboring peaks is smaller. The m/z range of each window is 10 FWHM.
