Spark OES for aluminum surfaces
When anodizing, the alloy of the workpiece is a decisive factor for the surface. For this purpose, spark OES can be used to quickly and reliably check whether the composition of the workpiece corresponds to the desired alloy.

Spark OES for technical safety
The area of technical safety also often involves the alloy composition of materials. A chemical composition that does not match the required alloy has different mechanical properties and can thus endanger the technical safety of components.
