摘要： 用微波等离子体炬(MPT)作激发光源,等离子体的工作气体为氩气,研究了气动雾化进样去溶系统的工作参数对分析性能的影响,探讨了水冷凝与浓硫酸吸收二者协同去溶的相关性.结果表明,通过测量OH带(Q1带,带头谱线为308.520nm)的发射强度即可判别样品去溶效果.

Abstract: Apneumatic nebulizer(PN) was utilized as a sample introduction device for the microwave plasma torch atomic emission spectrometry(MPT-AES) in an attempt to study the relationship between analytical performance and desolvation system. The desovation system consists of a condenser and a cell with concentrated H2SO4.Some parameters were studied and discussed in this work. The optimized conditions for the MPT-AESwere obtained.

Key words: Microwave plasma torch, Atomic emission spectrometry, Desovation system
