Procedure – Powder/Chip Samples

Instrument calibration/drift correction.

Calibrate/drift following the procedure outlined in the operator's instruction manual.

Login Sample with the appropriate number of reps.

Weigh approximately *** grams of appropriately prepared sample into a *** Nickel Capsule, enter mass and sample identification into appropriate rep fields. If applicable, place the nickel capsule in the

appropriate autoloader position.

Repeat steps 3c through 3i for sample analysis.

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.
