  abstract = 	{Non-thermal atmospheric pressure plasmas are a source of reactive components, such as electrons, ions, radicals, reactive and excited species, and photons. Typical application areas are surface or liquid treatments, which are based on additive or synergistic effects of these components and their transport at and across surfaces. However, knowledge about the isolated effect of each plasma component is rare. The isolated interaction of two different reactive components, ions and atomic oxygen, with surfaces or liquids, respectively, was investigated within this work. To study the isolated effect of ions on substrates at atmospheric pressure, the so-called vacuum-ultraviolet(VUV)-photoionization chamber has been developed. It uses a helium driven atmospheric pressure plasma to generate VUV photons with energies up to 21 eV, which are utilized to photoionize molecular species. Ion-based thin film deposition at atmospheric pressure can be utilized in this setup, e.g. by ionizing C2H2 molecules. Here it was shown that not only the parent C2H2+ ion is contributing to the thin film growth, but also clustered and polymerized ions. For atomic oxygen, its effective reaction with organic compounds in liquids is known. However, it was unknown whether these reactions are liquid-surface or volume dominated. Phenol solutions were used as a chemical probe to be treated by the effluent of the COST-Jet as a source of atomic oxygen. The comparison of experimental and modeling results revealed the predominance of reactions of atomic oxygen at the liquid surface.},
