Basics of Optical Emission Spectroscopy (OES)


Description

This course teaches the fundamentals of OES. Learn how plasma is generated, the spectrum is taken from the light, and how spectral lines are converted into element concentrations.

At the end you understand how OES works and what is important to consider when applying this technique to your sample material.
