GDS850A

Description
Glow Discharge Spectrometry utilizes a low-pressure, non-thermal process in which material is uniformly sputtered from the sample surface by a stream of argon ions. The sputtered material is then atomized and excited in a low-pressure plasma discharge, away from the sample surface. The GDS850A focuses this technology to enhance your lab’s performance for both process control and research/development investigations. It delivers highly accurate bulk analysis as well as quantitative depth profiling for coatings analysis and surface treatments. This instrument offers a spectral range from 120 to 800 nm and may be configured with up to 58 channels.

Features

• Separation of sputtering and excitation
• Linear calibration curves with wide dynamic range
• Lowered self-absorption and material re-deposition
• Excitation of almost exclusively atom lines
• Fewer and narrower emission lines reduce interference
• Freedom from metallurgical history
• Fewer standards required for calibration
• Low Ar gas consumption
• Automatic cleaning between samples

Highlight

Typical glow discharge sputter spot
Other methods may preferentially attack the sample surface and do not always provide a representative sample to analyze. With glow discharge, sample material is uniformly sputtered from the surface. The nonthermal nature of the sampling process makes this an excellent technique for difficult applications.
