Study on MIPT-AES with a Pneumatic Nebulization Sample Introduction System

Ye Dongmei Zhang Hanqi Jin Qinhan (Department of Chemistry, Jilin University, Changchun. 130023) Dong Defan (Hebei College of Geology, Shijiazhuang, 050031)  
The analytical characteristics of low-powered MPT-AES with a pneumatic nebulization sample introduction system were studied. The detection limits for Ag, Al, Ca, Cd, Cu, Fe and Mg were 31,17, 3.0, 6.7, 16, 5.1 and 3.1 ng/ml, respectively. The RSDs for determination of these elements were shown to be in the range of 1.7 to 5.3 %. The effect of some easily ionized elements on the Mg Ⅱ 279.6nm emission was investigated.
