LECO GDS900 Glow Discharge Atomic Emission Spectrometer

LECO’s Glow Discharge Spectrometer (GDS) offers you state-of-the-art technology designed specifically for routine elemental determination in most conductive ferrous and nonferrous materials. The GDS900 features improved performance, stability, accuracy, and precision in steel, iron (including as-cast), aluminum, copper, zinc, nickel, cobalt, tungsten, and titanium materials, while featuring our user-friendly Cornerstone® brand software to help streamline your analysis.


Glow Discharge Source Advantages

  • Simple, linear calibrations when compared to other sourcesGDS900 Lamp Area sm
  • Controlled excitation that occurs away from the sample surface
  • Reduced reference material consumption

Detection System Advantages

  • The inherent sensitivity, dynamic rangeGDS900 Spectrometer Area sm and linearity of CCD detectors coupled with the GD source ensures stability, flexibility, and performance for all bulk elemental applications
  • Full wavelength coverage from 160 nm to 460 nm
  • 50 pm (0.050 nm) resolution to differentiate even the most complex features of bulk spectra

System Level User Advantages
