LECO's GDS-750A

Applications:
Bulk analyses - ferrous and nonferrous metals in sheets, wire, or in-process. Depth profile analysis of thermochemical treatments, nitriding, carbonitriding, carburizing, galvanizing, coatings, and plating.

How it works:
The cathodic sputtering process of the Grimm-type lamp is created by applying a controlled voltage and current to the sample surface. Surface atoms removed by this sputtering process diffuse into the argon plasma where excitation and emission occurs. Separation of atom removal and excitation provides well-defined spectra which result in simple linear calibrations.

Product Features:
The GDS-750A is a 0.75 meter focal length, 58-channel spectrometer. It can provide quantitative information in as little as 30 seconds. Depth profiling capabilities are best at 10nm to 50µ m into the sample. High resolution scanning entrance slit provides background correction and poly-scan capabilities.

Other Benefits:

• Narrow, well-defined spectral lines.
• Low argon gas consumption
• Automatic cleaning of anode
• Optional RF source for metallic coatings of non-conductors or organic coatings on conductive material.
• 35" width allows spectrometer to fit through standard doors.
• Glow discharge is well know as an extremely stable excitation source that creates a very uniform sputter spot on the sample surface.
