Leco - Glow Discharge Atomic Emission Spectroscopy

Glow discharges are used as a source of light in devices such as neon lights, fluorescent lamps, and plasma-screen televisions. Analyzing the light produced with spectroscopy can reveal information about the atomic interactions in the gas, so glow discharges are used in plasma physics and analytical chemistry.

Available models

  • Separation of sputtering and excitation
  • Linear calibration curves with wide dynamic range
  • Minimized 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 argon gas consumption
  • Automatic cleaning between samples
  • Sample material is uniformly sputtered from the surface
  • Linear calibrations with wide dynamic range
  • Uniform sample excitation offers improved precision
  • Freedom from metallurgical history
  • Low argon gas consumption reduces cost per test
  • Quick matrix change with minimal memory effects
  • Automatic cleaning between analyses
  • Easy-to-use Windows®-based quality control software offers simple, linear calibrations and a flexible interface.
