Procedure - Solid 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 3j a minimum of three times for each calibration/drift standard used.
Calibrate/drift following the procedure outlined in the operator's instruction manual.
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.
Summary
The determination of the amount of oxygen, nitrogen, and hydrogen in iron, steel, nickel-, and cobalt-base alloys represents some of the most important quality metrics for these materials. Oxygen is used to create steel from pig iron by removing excess carbon. Oxygen content must be controlled to limit the amount of carbon monoxide that can be formed during solidification which may cause excessive porosity. Nitrogen is considered both an impurity as well as an important alloying agent. Itcan be present as a nitride or interstitially in its gaseous form. Increased nitrogen content is known to increase yield and tensile strength, thus decreasing ductility and formability. Excessive levels may evolve during solidification thus increasing porosity. High hydrogen content is the primary cause of embrittlement, blistering and flaking due to its high
mobility through the lattice and provides no potential alloying benefits. The ONH836 utilizes a high-power
electrode furnace to quickly and efficiently release the target gases from within the sample, which allows
for a very rapid simultaneous determination of oxygen, nitrogen, and hydrogen.
