LECO's glow discharge-optical emission spectrometers perform bulk and/or depth profile analyses on solid conductive samples. A RF source is available for analysis of non- conductors. GDS puts reliable analyses of bulk material and surface treatments in the hands of production personnel.
LECO's CCD-based Glow Discharge Optical Emission Spectrometer (GD-OES) offers you state-of-the-art technology designed specifically for routine elemental determination in most ferrous materials. The GDS500A features improved performance, stability, accuracy, and precision and it's rugged construction is designed to handle the rigors of a production environment.
• Uniform sample excitation offers improved precision
• Freedom from metallurgical history
• Low Ar gas consumption reduces cost per test
• Separation of sample sputtering from excitation
• Quick matrix change with minimal memory effects
• Auto cleaning between analysis

This SA-2000 surface analyzer brings the advanced capabilities of atomic emission spectroscopy to the production control environment for quantitative depth profiling. The SA-2000 is designed for determining the composition of conductive and non-conductive materials as a function of depth with a measurement range to 500 microns (best at 10 nm to 50 microns). It is an extremely user-friendly system and its software is hosted in a Microsoft® Windows® environment. Ideal for the analysis of surface-treated materials, it will perform bulk (24 elements nominal) as well as quantitative depth profile analysis.
