Flowing afterglow plasmas have found their interest in soft surface treatments of sensitive materials in life science as the sterilization of medical instruments. Variations of N,H and C-atoms density has been determined along the reduced pressure flowing afterglows of microwave R/N2-H2 and R/N2-CH4 discharges with R=N2, He and Ar. Density of H and C-atoms and other nitrogen-active species such as N2(A), N2(X,v>13),N2+,NH,N(2D), CN were obtained from that of N-atoms calibrated by NO titration, using the method of band intensity ratios in several conditions (between early and late afterglows). It has been obtained the density of O-atoms and NO molecules coming from air impurities. It has been deduced the wall destruction probability of H,O and C-atoms on the quartz afterglow tube: \(\gamma\)HR,N2=10-3,\(\gamma\)oR,N2=(0.4-1) 10-3 and \(\gamma_C^{N2}\)=(0.7)10-3. The effects of H and C-atoms on N-atoms inclusion inside TiO2 surfaces are reported.
