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。

分析软件同时包括实时的环境参数的监测，提供完整的系统图表的模拟。北京LECO氧氮氢分析仪哪家好

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.

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.
