The CCD-based GDS500A glow discharge optical emission spectrometer is designed for routine elemental determination in most ferrous and nonferrous materials. Windows-based software (designed for production use) includes QC tools and user-defined routines. Other advantages include full wavelength coverage from 165 to 464 nm; analysis of difficult materials including as-cast iron, powder metal parts, resulfurized/leaded steels and low-melting alloys; and controlled, nonthermal excitation away from the sample surface, which reduces chemical and metallurgical effects.
