Summary

The determination of the amount of oxygen, nitrogen, and hydrogen in iron, steel, nickel-, and cobalt-base alloys represents some of the most important quality metrics for these materials. Oxygen is used to create steel from pig iron by removing excess carbon. Oxygen content must be controlled to limit the amount of carbon monoxide that can be formed during solidification which may cause excessive porosity. Nitrogen is considered both an impurity as well as an important alloying agent. Itcan be present as a nitride or interstitially in its gaseous form. Increased nitrogen content is known to increase yield and tensile strength, thus decreasing ductility and formability. Excessive levels may evolve during solidification thus increasing porosity. High hydrogen content is the primary cause of embrittlement, blistering and flaking due to its high

mobility through the lattice and provides no potential alloying benefits. 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)該對連接點(diǎn)、焊點(diǎn)、閥門等進(jìn)行檢漏，以確保空氣中的氧不會反滲進(jìn)入管道及儀器內(nèi)部，造成測量數(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，同時確保連接取樣管路時沒有漏入空氣。

3、樣氣中氧含量的變化會受管道材質(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的不銹鋼管，而不用塑料管、橡膠管等。

4、微量元素分析時，要避免各種管件、閥門、表頭等死角對樣氣造成污染，因此必須盡可能的簡化氣路系統(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。
