Procedure – Powder/Chip 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 3i a minimum of three times for each calibration/drift standard used.

Procedure - Solid Samples：

--Instrument calibration/drift correction.

Place the nickel basket containing the calibration/drift standard into the open port at the top of the loading head.

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 manually, or, if applicable, remove the crucible and press the analyze button to clean with the automatic cleaner.

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 – Powder/Chip Samples

Instrument calibration/drift correction.

Calibrate/drift following the procedure outlined in the operator's instruction manual.

Analyze Samples.

Login Sample with the appropriate number of reps.

Weigh approximately *** grams of appropriately prepared sample into a *** Nickel Capsule, enter mass and sample identification into appropriate rep fields. If applicable, place the nickel capsule in the

appropriate autoloader position.

Repeat steps 3c through 3i for sample analysis.

氧氮氢分析仪的使用注意事项：

1 、氧氮氢分析仪在初次启用前，应该对连接点、焊点、阀门等进行检漏，以确保空气中的氧不会反渗进入管道及仪器内部，造成测量数值偏高。

2、再次使用仪器前，要进行管道系统净化，将漏入的空气除干净，同时确保连接取样管路时没有漏入空气。

3、样气中氧含量的变化会受管道材质及表面粗糙度影响，因此一般连接管路选用铜管或抛光过的不锈钢管，而不用塑料管、橡胶管等。

4、微量元素分析时，要避免各种管件、阀门、表头等死角对样气造成污染，因此必须尽可能的简化气路系统，连接件死角要小，以防止溶解氧逸出造成污染，使用水封、油封及腊封等设备，才能较好的确保数据的。
