Arc/Spark Optical Emission Spectroscopy

Arc/Spark Optical Emission Spectroscopy is an analytical technique used to obtain the elemental composition of different alloys with varying base materials.  An electrical arc is passed through a sample, under an argon atmosphere, heating and exiting the atoms within the material.  While discharging energy the atoms give off a characteristic wavelength of light that is detected and measured to obtain an accurate weight percentage of the elements present in the sample.

 

EPI-MTG has a Thermo Scientific ARL 3460 Metals Analyzer.  We are capable of analyzing metals that have a base material of Iron, Nickel, and Copper.
