Optical Emission Spectroscopy, or OES analysis, is a rapid method for determining the elemental composition of a variety of metals and alloys. Element’s chemical analysis labs are equipped and ready to evaluate the properties of your material.

OES analysis uses a sparking process, which involves applying an electrical charge to the sample, vaporizing a small amount of material. Once this spark occurs, a discharge plasma with a distinct chemical signature is created, allowing our experts to determine the elemental breakdown of the sample. Results of the analysis are given as a percentage breakdown of the constituent elements.

Considerations for Optical Emission Spectroscopy

Optical emission spectroscopy is an ideal choice for applications where knowing the exact, quantitative breakdown of a solid material is required. The best material types for OES analysis are metals that are soft enough to respond to the sparking process. Harder metals, which may be resistant to sparking, are better suited to other chemical analysis methods. The inherent accuracy and rapid delivery of results make OES analysis the ideal choice for lot verification testing of a wide range of alloys.
