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.

氧氮氢分析仪的常见故障及解决方法
供电正常、通讯正常,点击确认键后分析仪不工作。这是没有水流,炉子温度太高或仪器通道电压不正常。如没有水流,炉子温度太高这些信息会显示在显示器画面上,但没有信息显示说明这两项正常。接下来检查仪器通道零位电压,如果比±3V高出1V以上,可能是因为气瓶空了,或者是空气进入到分析仪中。检查并更换化学试剂,如果有空气进入热导池里,热导池的电压就会<-6V,此时打开右面的门,堵住炉子气体进口,10s后,热导池电压值必然升高。经过逐一排查,**终确认碱石棉有问题,更换后仪器正常。 Cornerstone氢氧氮分析软件同时支持***的书记文档格式和可变的报告格式。
Sample Preparation
Sampling and sample preparation of refractory metals such as titanium and zirconium is somewhat different from that of steel. Unlike steel samples, hydrogen is not as mobile in this group of materials; therefore, storage in liquid nitrogen or dry ice is not required. However, it is important to keep the sample cool when cutting or sectioning. Sample preparation for oxygen and nitrogen determination has beendifferent from that of hydrogen determination.
