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.

Procedure - Solid Samples

Instrument calibration/drift correction.

Place the calibration/drift standard in a *** Nickel Basket, and if applicable, place the sample into the appropriate autoloader position.

Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open.

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.

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。 OHN836系列仪器采用惰性熔融法。

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.

试样加载过程中完全密闭，消除大气的中可能带来的杂质的污染。山西美国分析仪哪家好
