Procedure - Solid Samples

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

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

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.

Procedure – Powder/Chip Samples

Instrument calibration/drift correction.

Calibrate/drift following the procedure outlined in the operator's instruction manual.

Analyze Samples.

Login Sample with the appropriate number of reps.

Weigh approximately *** grams of appropriately prepared sample into a *** Nickel Capsule, enter mass and sample identification into appropriate rep fields. If applicable, place the nickel capsule in the

appropriate autoloader position.

Repeat steps 3c through 3i for sample analysis.

Procedure - Solid Samples

Instrument calibration/drift correction.

Place the calibration/drift standard in a *** Nickel Basket, and if applicable, place the sample into the appropriate autoloader position.

Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open.

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.
