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 3 0 8.5 2 0 nm)的发射强度即可判别样品去溶效果 .
A pneumatic 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 H 2SO 4. Some parameters were studied and discussed in this work. The optimized conditions for the MPT AES were obtained.
