Sample Preparation
Typically, titanium and zirconium samples are chemically etched to remove surface contamination when oxygen and nitrogen are determined. However, etching can introduce hydrogen into the sample.
ASTM method E 1409 "Determination of Oxygen and Nitrogen in Titanium and Titanium Alloys by the Inert
Gas Fusion Technique", as updated in 1996, permits either etching or abrading (filing) of the test specimen.
ASTM E 1447 "Determination of Hydrogen in Titanium and Titanium Alloys by the Inert Gas Fusion Thermal
Conductivity/Infrared Detection Method" permits surface preparation by abrading (if necessary to remove
contamination). Differences in sample preparation present somewhat of a dilemma regarding simultaneous
determination of O, N, and H in titanium. However, abrading samples with a file to remove surface
contamination will yield accurate O, N, and H results. The ONH836 utilizes a high-power electrode furnace to quickly and efficiently release the target gases from within the sample, which allows for a very rapid simultaneous determination of oxygen, nitrogen, and hydrogen.
