Within this project, the know-how about quantitative depth profile analysis (QDP) using radio frequency glow discharge optical emission spectrometry (RF GD-OES) has been greatly advanced. Applied to a range of real-world industrial materials, it has been proven that QDP using RF GD-OES can indeed provide accurate quantitative information, indeed for very demanding applications where no alternative technique for rapid analysis exists. The understanding of the function of the existing RF sources and how to use them in practical analytical work has also been greatly advanced. The work produced the following accomplishments:

- It is shown that multi-matrix calibration of RF GD-OES systems can be accomplished in the same way as for DC systems.
- It is shown that QDP of conductive coatings can be accomplished with comparable accuracy using RF and DC systems.
- Suitable discharge conditions for a range of non-conductive coatings have been established.
- QDP of several types of non-conductive coatings has been carried out using three different types of RF sources, with generally very consistent results.
- The matrix connection algorithm introduced in the preceding method development project has proven its worth and necessity.
- The QDP results of non-conductive coatings have been verified against other analytical methods wherever possible, in most cases with very satisfactory results.
