Procedure – Powder/Chip Samples
Determine the instrument blank.
Press the Analyze button on the instrument screen again, the loading head slide-block will close and the lower electrode will open.
Clean the upper and lower electrode either manually or remove the crucible and press the analyze button to clean with an automatic cleaner if applicable.
Add approximately 0.05 g of *** Graphite Powder to a 782-720 Graphite Crucible.
Firmly place the crucible on the lower electrode tip or appropriate autoloader position.

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.
