电热进样微波等离子体原子吸收光谱法的性能研究

Study on the Performance of Microwave Induced Plasma Atomic Absorption Spectrometry with Electrothermal Sample-introduced Device

本文将L形放电-吸收管与电热进样微波诱导等离子体原子吸收光谱法相结合,考察了各种实验参数对分析性能的影响.给出了利用该方法测定一系列元素的特征浓度,讨论了共存元素等因素对检测结果的影响.将本法用于实际样品分析,结果较好.

In this paper, a method of MIP-AAS with electrothermal sample-introduced device is described. An L-shaped discharge-absorption tube was used as the atomization cell. The experimental parameters were optimized and the analytical figures of merit are discussed. The recommended method has been successfully applied to the analysis of several practical samples.
