Atmospheric non-equilibrium plasmas are an effective source of large densities of reactive radicals, metastables, ions and high fluxes of photons with wavelength down to the 60 nm. The resulting high reactivity of these plasmas is due to a combination of several or all of these components, very often in a synergistic way, during the treatment and it is the key factor for the success of these plasmas in plasma medicine applications. Especially important for the understanding of the plasma treatments is the study of isolated or combined effects of the plasma components. In this contribution, the mass spectrometry for detection of neutral and ionized species and the windowless VUV spectroscopy for the plasma analysis will be discussed in detail, followed by the discussion of plasma source designs for separation of different plasma components.
