Learn more about optical emission spectrometry

An industry-standard analytical solution for metallurgical applications, optical emission spectrometry is well-established for the analysis of a large range of metals and alloys (from Ag to Zn). It is the ideal technology for process and quality control in metal production and is routinely applied directly in-the-field for foundry production. Optical emission spectrometry offers the possibility to analyze elemental composition of alloys down to the trace level with minimal impact on operating throughput, ensuring precise and reliable readings for up to 40 individual alloying elements in a single minute. It is also possible to investigate non-metallic inclusions using advanced optical emission spectrometry methods.
