In conclusion, GD-OE S is a very versatile analytical technique which is still in a state of rapid technical development. In particular, the introduction of rf sources for non-conductive materials has opened up new areas of application. Further development of more advanced techniques, e. g. pulsed glow discharge operation combined with time-gated detection [4.217], is likely to improve the analytical capabilities of GD-OE S in the near future. [Pg.231]

Pulsed discharges may be utilized to analyze nonconductive samples. Steiner et al. described the use of a pin-type pulsed rf-GD in conjunction with a linear orthogonal extraction TOF-MS [58]. Figure 12.24 depicts differences in the spectra obtained 4.0 msec after the power plateau and 7.0 msec after the plateau. As expected, the sputtered species (Si) in the discharge are found in the afterpeak at 7.0 msec (see Fig. 12.24). The resolution and sensitivity of this early system were limited and improvements were planned in the input optical system of the instrument. [Pg.489]

Hanes and Bair have followed with NH2 absorption spectroscopy the recombination of NH2 produced in an Rf discharge pulse. Pressures were in the range of a few tenths of a torr. The overall primary process is assumed to be... [Pg.257]

The negative ions of all Pt group elements M have been mass spectrometrically detected using ionization (by a pulsed rf vacuum-spark discharge) of powders of Ru, Rh, Os, and Ir and of metals (or alloys) of Pd and Pt [1]. [Pg.260]
