电热进样微波诱导等离子体原子吸收光谱法进样装置的改进及测定铜的研究

Improvement of Sample Introduction Devices for Electrothermal MIP-AAS and the Determination of Copper

本文介绍将电热进样技术与L型放电—吸收管的MIP-AAS技术相结合,研究了三种类型进样装置的不同条件参数对测定Cu的影响,使ET-MIP-AAS这一技术灵敏度得到提高,精密度得到较好改善。

Three different sample introduction devices of electrothermal MIP-AAS are described The effects of different parameters of these devices on the determination of Cu have been investigated The experimental parameters of MIP-AAS are selected and optimized to improve the analytical performance of ET-MIP-AAS.
