AN ENHANCED PROCEDURE FOR CAST IRON (CI.) INVESTIGATION FOR PRECISE INVESTIGATION OF CARBON (C) AND A FEW OTHER ELEMENTS BY OPTICAL EMISSION SPECTROMETER

摘要

This technique is very functional for Analyzing chemical composition of sample in many Situations, including identifying and segregating metal types in outdoor metal recycling facilities, quality control testing in factories and forensic work. In this method when analyzing any sample on an Optical Emission Spectrometer. The sample is kept on the spark stand of the OES. After the initial Pre-burn period when sparking and combination start, the sample is moved using a stepper motor. It has been established that one gets good accuracy for all elements like Silicon (Si), Sulphur (S) & Phosphorus (P) including Carbon. All operations are automatic using software and timings are optimized.
