Glow discharge-optical emission spectrometry was developed and demonstrated for in situ measurement of the chemical composition of surfaces exposed to plasmas. While the array of analytical methods routinely applied for depth profile analysis was fairly static over the decades of the 1980s and 1990s, there appears to be an emerging technique that has a number of very positive and complementary attributes, A small coupon piece (aluminum coated with yttria in this study) was mounted on an rf-biased electrode and inserted into an opening in the reactor wall. It follows two sets of samples through the whole process of analysis, brass samples for bulk analysis, and zinc-coated steel for depth profiling. This process is very time-consuming and only a certain amount of automation is possible.
