OES ANALYSIS AND PMI OF ALUMINUM, IRON, NICKEL, COBALT, COPPER AND TITANIUM ALLOYS
OES analysis (Optical Emission Spectroscopy) uses quantitative measurement of the optical emission from excited atoms to determine analyte concentration. A solid sample is atomized by an arc-spark discharge which provides sufficient energy to promote the electrons of atoms into high energy levels.
The intensity of the light, which is proportional to the concentration of the element in the sample, is recalculated internally from a stored set of calibration curves and is shown directly as percent concentration of the element.
IMR's OES analysis services enables manufacturers and their suppliers to verify their materials composition. All analyses are NIST traceable through the use of certified reference materials. Typically element concentrations are reported to 0.01 wt%, however in some cases trace elements can be analyzed to ppm levels.
