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.

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。

Procedure – Powder/Chip Samples

Prepare the instrument as outlined in the operator's instruction manual.

Determine the instrument blank.

Login a minimum of three Blank reps.

Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Insert a *** Nickel Capsule (leave capsule open) into the open port at top of loading head.

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.

Procedure - Solid Samples

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

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

Sample Preparation

Typically, titanium and zirconium samples are chemically etched to remove surface contamination when oxygen and nitrogen are determined. However, etching can introduce hydrogen into the sample.

ASTM method E 1409 "Determination of Oxygen and Nitrogen in Titanium and Titanium Alloys by the Inert

Gas Fusion Technique", as updated in 1996, permits either etching or abrading (filing) of the test specimen.

ASTM E 1447 "Determination of Hydrogen in Titanium and Titanium Alloys by the Inert Gas Fusion Thermal

Conductivity/Infrared Detection Method" permits surface preparation by abrading (if necessary to remove

contamination). Differences in sample preparation present somewhat of a dilemma regarding simultaneous

determination of O, N, and H in titanium. However, abrading samples with a file to remove surface

contamination will yield accurate O, N, and H results. The ONH836 utilizes a high-power electrode furnace to quickly and efficiently release the target gases from within the sample, which allows for a very rapid simultaneous determination of oxygen, nitrogen, and hydrogen.
