Glow discharge spectrometers use a low-pressure process to sputter material from the surface of a sample using a gas such as argon. The atoms in this sputtered material emit a light that can be analyzed using spectrometry techniques. This type of analysis is beneficial for studying a material’s composition without changing the chemistry of the sample being analyzed. This also eliminates the need for lengthy sample preparation steps. Glow discharge spectrometers are especially useful for their ability to perform rapid analyses on films and coatings.

| 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 GDS-850A 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 GDS-850A focuses this technology to enhance your lab’s performance for both process control and research and 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.
