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.

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.

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(gè)不同靈敏度的探測(cè)器，在更多的應(yīng)用中保證了準(zhǔn)確度。

操作簡(jiǎn)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(dòng)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(dòng)，然后樣品逐漸落入加熱區(qū)。通過添加載體氣體氮?dú)?，氫氣被擴(kuò)散出來并且隨載體被傳導(dǎo)至一個(gè)高靈敏度的熱傳導(dǎo)測(cè)量池。

通常一次測(cè)量的時(shí)間在3到15分鐘之間。在分析的過程中設(shè)備可以顯示測(cè)試信號(hào)和設(shè)備的參數(shù)，從信號(hào)的評(píng)估到結(jié)果在界面上的顯示全部自動(dòng)完成；而測(cè)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。
