Rapid depth-resolved analysis of nitride layers (>50 micrometers) on prosthetic devices by radio prequency glow discharge atomic emission spectroscopy

摘要

The ability to provide depth-resolved chemical information is an important attribute for analytical methods employed in the biomaterials laboratory, both research and production. Radio frequency glow discharge atomic emission spectroscopy (rf-GD-AES) is shown to provide profiles of nitrogen content in prosthetic alloys to depths of greater than 50 micrometers, with analysis times of less than 30 minutes.
