Optical Emission Spectroscopy | Full Explanation & Precautions

Are you working with metals and need to know their elemental composition and verify their grade? Then you're in for a treat, because today we're diving into the world of Optical Emission Spectroscopy, also known as OES.

Optical Emission Spectroscopy is a powerful analytical tool that uses the principles of atomic emission to determine the elemental composition of metals and alloys with extreme accuracy. Specifically, we will be looking at the Spark-OES technique in this video.

But that's not all. OES has numerous benefits, from detecting trace elements and impurities, to ensuring the consistency and quality of materials used in various industries.

So, if you want to gain a deeper understanding of the principles and the causes for error, then join me in this journey as we carry out a testing of a Stainless Steel material.

The test methods that use the spark emission spectroscopy are:
ASTM E1251
ASTM E1999
ASTM E1476
IS 8811
ASTM E415
and more
