Chemical Analysis

Chemical Analysis is utilized to determine not only type, but quantity of a wide variety of elements which comprise a part. Chemical Analysis yields the chemical composition, which in turn can be used to determine things such as the carbon equivalent (CE) in welding, strength related properties, hardenability in the heat treatment industry, and the pitting resistance equivalent related to corrosion resistance. One example of determining chemical composition offered by Steel City NDT5 Cool, Practical Uses for Phased Array Antennas and Transducers. Read more ... ยป LLC is Optical Emission Spectrometry. This involved applying electrical energy in the form of a spark generated by an electrode and a metal sample. This creates a discharge plasma which, in turn, creates a unique emission spectrum to each element. Light generated by the discharge is split by a diffraction grating to extract the emission spectrum for the target elements. In intensity of each emission depends on the concentration of the element in the sample.
