Method Selection

Two methods are described in this application note; either method can be used to analyze iron, steel, nickel-, and cobalt-base alloys. The Precision Method is recommended for general use and will provide the best precision and accuracy throughout the typical O, N, and H concentrations found in this group of metals; approximate cycle time is 3.5 minutes. The Fast Track method can be used where speed of analysis is a critical component; for example, when molten metal is being sampled and results are required in the shortest possible time. This method will produce suitable results for most samples; approximate cycle time is 2.25 minutes. As noted above, sampling and sample preparation are key elements to accurate O, N, and Hdetermination as well. It is up to the user to determine which method best meets their needs.

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。

Procedure - Solid Samples

Prepare the instrument as outlined in the operator's instruction manual.

Determine the instrument blank.

Login a minimum of 3 Blank replicates.

Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Place a 502-344 Nickel Basket into the loading head.

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.
