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.
Determine the instrument blank.
a. Login a minimum of 3 Blank replicates.
b. Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open.
c. Press the Analyze button on the instrument screen again, the loading head slide-block will close and the lower electrode will open.
d. Clean the upper and lower electrode manually, or, if applicable, remove thecrucible and press the analyze button to clean with the automatic cleaner.
e. Firmly place a graphite crucible on the lower electrode tip.
f. Press the Analyze button on the instrument screen, the lower electrode will close and the analysis sequence will start and endautomatically.
g. Repeat steps 2b through 2f a minimum of three times.
h. Set the blank following the procedure outlined in the operator's instruction manual.

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.
