Glow discharge optical emission spectrometry (GD-OES): an alternative technique for depth profiling-investigation of surface properties from the nanometer to the micrometer scale

摘要

Glow Discharge Spectroscopy (GDS) is a direct analysis technique used to measure the elemental concentrations of solid materials. Glow Discharge offers an improved excitation source for fast, economical, and reliable sample turnaround (in as little as one minute) with excellent accuracy and precision. The source uniformly removes material from the sample surface, which reduces the effects of metallurgical and chemical history inherent in all samples. The large dynamic range allows the determination of major, minor, and trace elements.
