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.

氧氮氢分析仪的使用注意事项：

1 、氧氮氢分析仪在初次启用前，应该对连接点、焊点、阀门等进行检漏，以确保空气中的氧不会反渗进入管道及仪器内部，造成测量数值偏高。

2、再次使用仪器前，要进行管道系统净化，将漏入的空气除干净，同时确保连接取样管路时没有漏入空气。

3、样气中氧含量的变化会受管道材质及表面粗糙度影响，因此一般连接管路选用铜管或抛光过的不锈钢管，而不用塑料管、橡胶管等。

4、微量元素分析时，要避免各种管件、阀门、表头等死角对样气造成污染，因此必须尽可能的简化气路系统，连接件死角要小，以防止溶解氧逸出造成污染，使用水封、油封及腊封等设备，才能较好的确保数据的。
