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 - Solid Samples：
--Instrument calibration/drift correction.
Place the nickel basket containing the calibration/drift standard 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 manually, or, if applicable, remove the crucible and press the analyze button to clean with the automatic cleaner.
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.
