Procedure - Solid Samples
Prepare the instrument as outlined in the operator's instruction manual.
Determine the instrument blank.
Login a minimum of 3 Blank replicates.
Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Place a 502-344 Nickel Basket into the 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.

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.
