Glow Discharge Atomic Emission Spectrometer
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 GDS850 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 compositional 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.
