氧氮?dú)浞治鰞x的使用注意事項(xiàng)：

1 、氧氮?dú)浞治鰞x在初次啟用前，應(yīng)該對(duì)連接點(diǎn)、焊點(diǎn)、閥門(mén)等進(jìn)行檢漏，以確?？諝庵械难醪粫?huì)反滲進(jìn)入管道及儀器內(nèi)部，造成測(cè)量數(shù)值偏高。

2、再次使用儀器前，要進(jìn)行管道系統(tǒng)凈化，將漏入的空氣除干凈，同時(shí)確保連接取樣管路時(shí)沒(méi)有漏入空氣。

3、樣氣中氧含量的變化會(huì)受管道材質(zhì)及表面粗糙度影響，因此一般連接管路選用銅管或拋光過(guò)的不銹鋼管，而不用塑料管、橡膠管等。

4、微量元素分析時(shí)，要避免各種管件、閥門(mén)、表頭等死角對(duì)樣氣造成污染，因此必須盡可能的簡(jiǎn)化氣路系統(tǒng)，連接件死角要小，以防止溶解氧逸出造成污染，使用水封、油封及臘封等設(shè)備，才能較好的確保數(shù)據(jù)的。

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.

736 Series: Oxygen/Nitrogen by Inert Gas Fusion

The 736 family of Elemental Analyzers is designed for routine measurement of oxygen and nitrogen content of

inorganic materials, ferrous and nonferrous alloys, andrefractory materials using the inert gas fusion technique.

These instruments feature our Cornerstone brand ® software, a custom interface designed specifically for

touch-screen operation. Developed by combining longterm research with customer feedback, this easy-to-use

software gives you complete access to instrument control, analysis settings, diagnostics, reporting, and more—without sacrificing valuable bench space.
