Selected ion signals from μ-APPJ (0.7 slm He, U rms =160 V, d=2 mm) in dependence on the distance to the sampling orifice orifice. The assignments in square brackets are corresponding to the most likely ion. For clarity the ions are separated into to groups summarizing (a) non-water and (b) water-containing ions. The dashed lines show the expected trends for N + and NO + based on reactions (4) and (10), respectively
