DETERMINATION OF METAL COMPOSITION VIA SPARK OPTICAL EMISSION SPECTROSCOPY (SPARK-OES)
Optical emission spectrometry involves applying electrical energy in the form of spark generated between an electrode and a metal sample, whereby the vaporized atoms are brought to a high energy state within a so-called “discharge plasma”.
This method involves statistical processing of the spark pulse-generated emission spectra obtained from spark discharges in an argon atmosphere. Light from the spark discharge is carried by fiber optics to the sensors, where the wavelengths and intensities of the several spectrum constituents are detected and measured. The optical emission spectrometer offers rapid elemental analysis of solid metal samples, making it indispensable for quality control in steel making and aluminum metallurgy processes.

Spark Optical Emission Spectroscopy
Optical Emission Spectroscopy, or OES, is a well trusted and widely used analytical technique used to determine the elemental composition of a broad range of metals, tubes, bolts, rods, wires, plates and many more.
X-Ray Florescence Method
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials.
