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.

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.

氧氮氢分析仪的操作过程
氧氮氢分析仪可根据的用户的要求定制。该分析仪配备两个不同灵敏度的探测器，在更多的应用中保证了准确度。
操作简单而且安全。在样品称重以后，样品的重量数据通过电子界面传导至相连的电脑中，也可以在软件界面中手动输入样品的重量。
样品被放置在水平放置的炉子中的低温区域。分析开始以后，炉子开始向上转动，然后样品逐渐落入加热区。通过添加载体气体氮气，氢气被扩散出来并且随载体被传导至一个高灵敏度的热传导测量池。
通常一次测量的时间在3到15分钟之间。在分析的过程中设备可以显示测试信号和设备的参数，从信号的评估到结果在界面上的显示全部自动完成；而测量数据则被传导至LIMS（实验室信息管理系统）中。无需过多的保养和维护，而除尘器和净化管的维护工作也方便。
