“…The applicability of rf-GD-MS (quadrupole mass analyser) for bulk and depth profile analysis of polymeric materials has also been demonstrated by Marcus and co-workers [37,117,118]. For example, a series of PTFE-based polymers were studied to assess their fingerprint mass spectra and to distinguish each sample by its differing base peaks and relative peak intensities [117].…”

The enormous potential of radiofrequency glow discharges (rf-GD) as photon, atom, or ion sources, coupled to spectrometric techniques, for rapid direct analysis of almost any conductor, semiconductor, or insulating material with good in-depth resolution has been demonstrated world-wide. This outstanding performance has prompted a great effort to develop and characterise rf-GD for direct materials analysis in recent years. The state of the art of rf-GD coupled to atomic absorption spectrometry, optical emission spectrometry, and mass spectrometry for direct solid analysis is reviewed here. A description of the principles of operation of the rf-GD and attempts to model these discharges are also given. Rf-GD instrumentation, both developed at research laboratories and commercially available, is described. Several practical examples are given demonstrating the capabilities of these techniques for bulk and depth-profile analysis. Finally, the research gaps to be filled for full implementation of rf-GD spectrometric techniques in industry and research centres alike for materials science studies and technical development are discussed.

“…In addition, cryogenic cooling of polymer samples during rf-GDMS analysis increases the scope of applicability of this technique to thermally sensitive materials, such as polyethylene films. 33 The technique has also been shown to be very reproducible, with the use of internal referencing of characteristic fragments of fluoro-and hydrocarbon polymers yielding variations of Ͻ5% RSD for multiple analyses. 35 Finally, as with SIMS, the sputter ablation step permits the depth-resolved analysis of polymers, with typical sputtering rates of 0.1-1.0 m/min and depth resolving powers on the order of 50 nm.…”

“…Several modifications to the existing flat-type sample holder assembly were necessary to provide for additional cooling of polymer samples. 33 In summary, a copper coolant block was placed behind the sample, which allowed for the passage of liquid nitrogen (LN 2 ) to cool the sample to temperatures of approximately Ϫ170°C.…”

The secondary neutrals are then ionized in the negative glow region of the GD by collisions with either electrons or argon metastable atoms.…”

A radio frequency glow discharge mass spectrometry (rf-GDMS) source is evaluated for future applications in the "fingerprint" characterization of polyphosphazene membranes. The rf-GDMS spectra of a series of bis(phenoxy)phosphazene polymers contain ions that originate from both the phosphazene backbone and the phenoxy moiety, resulting in signature ions of the polymer family. "Fingerprint" ions from the substituted R-group on the phenoxy moiety of the different derivatives allows the individual polymers to be distinguished from one another. The ability of the rf-GDMS source to characterize these materials directly in the solid state will be useful for the continued application of these polymers as separation membranes.

This feature article is focused on the application of secondary ion mass spectrometry (time-offlight SIMS) to the chemical and structural study of plasma-treated organic surfaces and plasma polymer films. After a brief historical perspective and a presentation of the recent developments of SIMS, illustrative case studies involving plasma-treated polymer surfaces and plasma polymers are presented. Beyond surface analysis by static SIMS, we show the potential of molecular depth-profiling by low-energy Cs þ ions and large Ar n þ clusters for the in-depth chemical characterization of plasma-modified samples. Together with SIMS data processing by multivariate analysis, molecular depth-profiling could provide a step change for the analysis of films treated or polymerized with plasmas.
