LECO Solutions for Glow Discharge

Atomic Emission Spectroscopy can determine elemental content of solid conductive materials. The GDS900 is designed to analyze ferrous and nonferrous metals, including cast iron.

Glow discharge spectrometry (GDS) is capable of analyzing all types of cast irons while other techniques, especially spark-emission spectrometry, commonly struggle in this area.

ASTM E1009 is used to determine both accuracy and precision of a spectrometer using Certified Reference Materials with proven homogeneity and which have been established as satisfactory for calibration.

Precise measurement of carbon in carburized steel can be challenging due to changing concentrations throughout the hardened case of a sample. Glow discharge spectroscopy (GDS) offers a repeatable ability to measure carbon in a region spatially discrete from organic carbon on the near surface and in the base material. The presentation includes comparisons to other measurements, relationships to microhardness measurements, and characterization of the materials with GDS compositional depth profiles and bulk analyses.
