Quantitative Depth Profiling
Using Glow Discharge Optical Emission Spectroscopy
The only true method to obtain quantitative chemical information as a function of depth. Unlike ESCA/XPS, QDP corrects for sputter rate variations in multi-matrix samples and produces continuous spectral data during the sputtering process.
Example Solutions
The following are typical QDP applications for materials processing, product development and QC/QA documentation activities.
- PVD coating
- Chrome plating
- Carbon / nitrogen surface hardening
- Zinc electroplating, hot-dip, Galvalume™...
- Surface de-carburization
- Contamination at coating interfaces
- Coating thickness / weight
- Chemical composition of coating layers
