Procedure – Powder/Chip Samples
Prepare the instrument as outlined in the operator's instruction manual.
Login a minimum of three Blank reps.
Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Insert a *** Nickel Capsule (leave capsule open) into the open port at top of loading head.
Note: samples using automation should be placed in the appropriate autoloader position before starting the analysis sequence. Once the sequence has started, the automatic analysis will start and end automatically.
Procedure – Powder/Chip Samples
Instrument calibration/drift correction.
Add approximately 0.05 g of *** Graphite Powder to a***Graphite Crucible.
Firmly place the crucible on the lower electrode tip or appropriate autoloader position.
Press the Analyze button on the instrument screen,the lower electrode will close and the analysis sequence will start and end automatically.
Repeat steps 3b through 3i a minimum of three times for each calibration/drift standard used.

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.
736 Series: Oxygen/Nitrogen by Inert Gas Fusion
The 736 family of Elemental Analyzers is designed for routine measurement of oxygen and nitrogen content of
inorganic materials, ferrous and nonferrous alloys, andrefractory materials using the inert gas fusion technique.
These instruments feature our Cornerstone brand ® software, a custom interface designed specifically for
touch-screen operation. Developed by combining longterm research with customer feedback, this easy-to-use
software gives you complete access to instrument control, analysis settings, diagnostics, reporting, and more—without sacrificing valuable bench space.

Oxygen, Nitrogen, and Hydrogen in Refractory Metals
Summary
One of the most critical chemical specifications of titanium alloys is the hydrogen content. Too high of a
hydrogen content can cause hydrides to precipitate, which can lead to embrittlement and subsequent
cracking when the alloy is stressed. Hydrogen pickup typically occurs during downstream processing steps
such as heat treating, pickling, and cleaning.
The LECO ONH836 is a simultaneous oxygen, nitrogen, and hydrogen determinator that utilizes an electrode furnace, inert carrier gas, and both infrared and thermal conductivity detection to meet the analytical needs of the refractory metal industry.
This application note was written specifically for use with the LECO ONH836 series determinator.
