Abstract

Overview

ISO 17053:2005 specifies an infrared (IR) method after fusion under inert gas for the determination of oxygen in steel and iron. The standard covers the analytical procedure in which a test portion is fused in a single-use graphite crucible under high-purity helium, oxygen is converted to CO (and CO2), and the resulting gas is measured by infrared absorption against potassium nitrate calibration standards. The method is applicable to oxygen mass fractions from 0.00075 % to 0.01 %.

Key topics and technical requirements

Principle: Fusion of a ~1 g test portion under helium at a minimum temperature of 2000 °C; oxygen reacts with graphite to form CO which is measured by IR detection (CO or CO2).
Reagents & gases: High-purity helium (total impurities ≤ 0.0005 %), potassium nitrate (KNO3) calibration solutions, drying agents (magnesium perchlorate or anhydrous calcium sulfate), ascarite (NaOH on support), and CuO catalyst when required.
Apparatus: Single-use graphite crucible, micropipette (100 µl, error
