一种在线微量氮气分析器

An online trace nitrogen Analyzer

在与氩气等放电气体接触的两个电极之间施加足够高的射频电压来使放电气体击穿,产生正电荷离子和自由电子。在离子化气体即等离子体环境中的N_2等分子被离解为原子。正电荷离子、自由电子在电场的作用下分别加速移向阴极、正极。通过碰撞,加速离子与电子将其能量传递给原子,原子被激发。气态原子被激发以后,其外层电子辐射跃迁将发射特征辐射能,即特征光谱。通过对特征光谱进行分析,从而确定元素类别及其含量。

in contact with Argon discharge gas high enough frequency voltage is applied between the two electrodes to make the discharge of gas breakdown, resuhing in positively charged ions and free electrons. In the ionized gas in the plasma environment of N2 mol- ecules dissociated into atoms. Positively charged ions, respectively in the presence of an electric field to accelerate free electrons move to the cathode and the anode. Collision, accelerated ion and electron passes its energy to the atoms,the atoms are excited. After gaseous atoms excited,its outer electron radiation emission characteristics of radiant energy, a characteristic spectrum. By analysis of characteristic spectra to determine the categories and content of an element.
