4. Characteristics of SDL compared with other surface analysis methods
Comparing techniques of very different design is always a difficult exercise, especially as there are so many surface analysis methods available today. The idea here, therefore, is not to set out the principles of these different methods, but to try and present the advantages and limitations of glow discharge spectrometry compared with the few techniques in this group, which have seen significant development in industry and are used in the field of treated or coated surfaces.

Device example
Features of the Horiba Jobin-Yvon GD-Profiler 2 spectrometer
The device is built around a 47-channel simultaneous polychromator with a 2,400 tr/mm double-order concave holographic grating, 0.5 m focal length and 18 to 25 pm resolution in the 110 to 600 nm spectral range. In the UV, the elements measured are H (and D, deuterium, an isotope of H), O, C, N, Cl, Br, I.
