Optical Emission Spectrometry is an analytical technique used to determine the elemental composition of metals and alloys. It works on a simple physical principle: every chemical element, when excited with enough energy, emits light at wavelengths that are unique to it — almost like a fingerprint.
An OES spectrometeruses this principle to identify and measure the concentration of elements such as carbon, manganese, chromium, nickel, silicon, copper, and dozens of others present in a metal sample, typically within seconds.
This makes OES one of the fastest and most reliable methods available for elemental analysis in industrial settings, especially where quality control decisions need to be made in real time — during melting, before pouring, or before a batch is released for shipment.
