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 – Powder/Chip Samples
Determine the instrument blank.
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.
Add approximately 0.05 g of *** Graphite Powder to a 782-720 Graphite Crucible.
Firmly place the crucible on the lower electrode tip or appropriate autoloader position.
氧氮氢分析仪的常见故障及解决方法
仪器启动时显示。没有水流。系统分析电流切断，分析停止。这是水流探测器不正常，水泵不工作，管道堵塞。将仪器的右面板取下，观察水流探测器，用手挤压补水塑料水瓶，发现水流正常，显示正常，证明水流探测器正常，管道畅通。启动循环水泵，但分析仪显示没有水流，此时可判定水泵不正常。打开水泵转子密封口，启动泵发现电机正常运转，此时关闭进水，拆下水泵，发现叶轮脱落。经了解，判定是由于外部冷却水停水，仪器内循环水温过高（水温应≤70℃），致使叶轮（叶轮材料PVC）热胀并脱轴。用粘合剂粘合叶轮后再粘于叶轮轴上，待粘合剂凝固后试车，仪器运行正常。
Instrument calibration/drift correction
f. Clean the upper and lower electrode manually, or, if applicable, remove the crucible and press the analyze button to clean with the automatic cleaner.
g. Firmly place a graphite crucible on the lower electrode tip.
h. Press the Analyze button on the instrument screen, the lower electrode will close and the analysis sequence will start and end automatically.
i. Repeat steps 3b through 3h a minimum of three times for each calibration/drift standard used.
. Calibrate/drift following the procedure outlined in the operator's instruction manual.
Procedure – Powder/Chip Samples
Determine the instrument blank.
Press the Analyze button on the instrument screen, the lower electrode will close and the analysis sequence will start and end automatically.
Repeat steps 2b through 2g a minimum of three times.
Set the blank following the procedure outlined in the operator's instruction manual.
Instrument calibration/drift correction.
Login a minimum of three Standard reps.
Weigh approximately *** grams of a calibration/drift standard into a *** Nickel Capsule; enter the mass and standard identification into appropriate rep fields. If applicable, place the nickel capsule in the appropriate autoloader position.
