Chemical Analysis

Our chemical Lab also employs X-Ray, Atomic Absorption, Optical Emission & Ultra-voilet visible Spectrometry and gas analysis, wet Chemistry. Optical Emission Spectrometry (OES or Arc Spark) for routine analysis of metals and their alloys. The OES has been designed specifically to meet the demands of quality in Iron, Cobalt, Titanium and Nickel-based alloys (ASTM E353).

Carbon, Sulfur, Hydrogen, Oxygen, and Nitrogen content in steel and titanium is determined by the inert gas fusion thermal conductivity method (ASTM E1019 and ASTM E1447) utilizing Leco instrumentation.

Chemical compositional analysis is also carried out using X-ray Fluorescence Spectrometry, PMI, semi-quantitative analysis using Mobile Optical Emission Spectrometry.
