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.

Sample Preparation

Sampling and sample preparation is an important issue because traditional methods used to obtain samples for oxygen and nitrogen determination are different from those recommended for hydrogen, especially when sampling molten metal. The main difference in steel sampling procedures for oxygen/nitrogen and hydrogen is due to the mobilityof hydrogen. Special precautions must be used when sampling for hydrogen. From molten steel and iron, a sample must be quickly quenched in cold water and chilled in a refrigerant such as liquefied nitrogen or a mixture of acetone and solid carbon dioxide in order to reduce losses of hydrogen from diffusion. Losses of oxygen and nitrogen from diffusion are not a problem. A sample that is taken for hydrogen and

chilled in a refrigerant can also be used for oxygen and nitrogen determination. However, a sample that is typically taken for oxygen and/or nitrogen determination is not suitable for hydrogen determination due to hydrogen loss (diffusion). Surface contamination must be removed by filing or light grinding, using care not to overheat the sample.

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。 无需人工干预的全自动清扫系统。
