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

Instrument calibration/drift correction.

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

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?dú)浞治鰞x的操作過程

氧氮?dú)浞治鰞x可根據(jù)的用戶的要求定制。該分析儀配備兩個不同靈敏度的探測器，在更多的應(yīng)用中保證了準(zhǔn)確度。

操作簡單而且安全。在樣品稱重以后，樣品的重量數(shù)據(jù)通過電子界面?zhèn)鲗?dǎo)至相連的電腦中，也可以在軟件界面中手動輸入樣品的重量。

樣品被放置在水平放置的爐子中的低溫區(qū)域。分析開始以后，爐子開始向上轉(zhuǎn)動，然后樣品逐漸落入加熱區(qū)。通過添加載體氣體氮?dú)猓瑲錃獗粩U(kuò)散出來并且隨載體被傳導(dǎo)至一個高靈敏度的熱傳導(dǎo)測量池。

通常一次測量的時間在3到15分鐘之間。在分析的過程中設(shè)備可以顯示測試信號和設(shè)備的參數(shù)，從信號的評估到結(jié)果在界面上的顯示全部自動完成；而測量數(shù)據(jù)則被傳導(dǎo)至LIMS（實(shí)驗(yàn)室信息管理系統(tǒng)）中。無需過多的保養(yǎng)和維護(hù)，而除塵器和凈化管的維護(hù)工作也方便。

Method Selection

Two methods are described in this application note; either method can be used to analyze iron, steel, nickel-, and cobalt-base alloys. The Precision Method is recommended for general use and will provide the best precision and accuracy throughout the typical O, N, and H concentrations found in this group of metals; approximate cycle time is 3.5 minutes. The Fast Track method can be used where speed of analysis is a critical component; for example, when molten metal is being sampled and results are required in the shortest possible time. This method will produce suitable results for most samples; approximate cycle time is 2.25 minutes. As noted above, sampling and sample preparation are key elements to accurate O, N, and Hdetermination as well. It is up to the user to determine which method best meets their needs.
