摘要

研制了一种用于金属固体样品直接激发的小型等离子体喷射燃烧器。最佳操作条件为:直流电弧电流约15 A，氮气切向引入气体流量约1.5-2 l/min，雾化器气体流量约3.5-4 l/min。用溶液样品测定了某些元素的检出限。对某些固态合金中合金元素的分析也获得了满意的校正曲线。

Emission Spectrographic Analysis of Metal Solid Samples with Plasma Jet Flame. I. : Application of Nitrogen Plasma Flame

A small plasma jet burner for direct excitation of metal solid samples was developed. The optimum operating conditions are as follows; d.c. arc current about 15 A, flow rate of nitrogen tangentially introduced gas about 1.5–2 l/min, and that of atomizer gas about 3.5–4 l/min. The limit of detection of some elements were determined with solution samples. Satisfactory-calibration curves were also obtained for analyses of alloying elements in some solid form alloys.
