How to Prepare Metal Samples for OES Spectrometer | Ferrous & Non-Ferrous Metals
Apr 02 , 2026
Learn the standard sample preparation method for Optical Emission Spectrometer (OES) for accurate metal analysis.This video covers proper preparation for ferrous metals (steel, iron, cast iron) using grinders, and non-ferrous metals (aluminum, copper, magnesium) using a lathe.
Key points:
Clean, flat, oxide-free surface
Fresh metallic luster for excitation
Avoid rust, discoloration, pits and cracks
Test immediately after preparation
Safety precautions for grinding & lathe operation
Perfect for metallurgy, quality control, foundry, and metal testing labs
