Function of Optical Emission Spectrometer
 

In optical emission spectroscopy, a metal is heated to high temperature using electrical discharge; the light emitted by the metal atoms in the sample is then passed through a spectrometer, which splits the light up with a prism or diffraction grating. The pattern of bands cast by the spectrometer can be used to identify the element.

Tensile testing, also known as tension testing, is a fundamental materials science test in which a sample is subjected to uniaxial tension until failure. The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under other types of forces. Properties that are directly measured via a tensile test are ultimate tensile strength, percentage elongation and percentage reduction in area. Tensile testing includes tensile test with 0.2% proof stress, Yield Stress, % Elongation, %Reduction area.
