Procedure – Powder/Chip Samples
Instrument calibration/drift correction.
Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open.
Place the Nickel Capsule containing the sample into the open port at the top of the loading head.
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.

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.
Procedure - Solid Samples
Determine the instrument blank.
Repeat steps 2b through 2g a minimum of three times.
Set the blank following the procedure outlined in the operator's instruction manual.
Instrument calibration/drift correction.
Login a minimum of 3 Standard replicates.
Weigh approximately *** grams of a calibration/drift standard, enter the mass and standard identification into appropriate replicate fields.
Note: LECO Reference Materia***o not require preparation.See preparation statement on the reference material certificate.

Sample Preparation
Sampling and sample preparation of refractory metals such as titanium and zirconium is somewhat different from that of steel. Unlike steel samples, hydrogen is not as mobile in this group of materials; therefore, storage in liquid nitrogen or dry ice is not required. However, it is important to keep the sample cool when cutting or sectioning. Sample preparation for oxygen and nitrogen determination has beendifferent from that of hydrogen determination.
