Laboratories of Atomic Spectroscopy are designed for the analysis of the chemical composition of both solid materials (metals) and solutions.
The chemical composition of steels, cast irons, and aluminum alloys is a fundamental parameter of these materials. Optical emission spectroscopy with glow discharge (GDOES) provides precise chemical composition data with minimal thermal impact on the base material. The sample for analysis must be compact, flat (or grindable), with a minimum diameter of 1.5 cm and a maximum of 20 cm. The maximum thickness is 3 cm. This is a partially destructive method – material sputtering occurs (a "burned spot" with a diameter of 4 mm remains on the material). The GDA 750 also enables depth profile analysis, which provides a graphical representation of the chemical composition of the material over analysis time (for galvanized material, also with respect to depth). Flat compact materials with surface treatments (galvanized, chrome-plated, aluminized, etc.) can also be analyzed.
