Method Selection

Two methods are described in this application note; either method can be used to analyze iron, steel, nickel-, and cobalt-base alloys. The Precision Method is recommended for general use and will provide the best precision and accuracy throughout the typical O, N, and H concentrations found in this group of metals; approximate cycle time is 3.5 minutes. The Fast Track method can be used where speed of analysis is a critical component; for example, when molten metal is being sampled and results are required in the shortest possible time. This method will produce suitable results for most samples; approximate cycle time is 2.25 minutes. As noted above, sampling and sample preparation are key elements to accurate O, N, and Hdetermination as well. It is up to the user to determine which method best meets their needs.

Sample Preparation

Sampling and sample preparation is an important issue because traditional methods used to obtain samples for oxygen and nitrogen determination are different from those recommended for hydrogen, especially when sampling molten metal. The main difference in steel sampling procedures for oxygen/nitrogen and hydrogen is due to the mobilityof hydrogen. Special precautions must be used when sampling for hydrogen. From molten steel and iron, a sample must be quickly quenched in cold water and chilled in a refrigerant such as liquefied nitrogen or a mixture of acetone and solid carbon dioxide in order to reduce losses of hydrogen from diffusion. Losses of oxygen and nitrogen from diffusion are not a problem. A sample that is taken for hydrogen and

chilled in a refrigerant can also be used for oxygen and nitrogen determination. However, a sample that is typically taken for oxygen and/or nitrogen determination is not suitable for hydrogen determination due to hydrogen loss (diffusion). Surface contamination must be removed by filing or light grinding, using care not to overheat the sample.
