摘要
Abstract
In current undergraduate education for chemistry majors,the teaching experiments related to elemental analysis in the"Instrumental Analysis"course mainly rely on the use of commercial instruments such as Atomic Absorption Spectroscopy(AAS),Atomic Fluorescence Spectrometry(AFS),and Inductively Coupled Plasma Mass Spectrometry(ICP-OES).While these instruments effectively cover the teaching requirements for understanding the basic principles of analytical instruments,they are often expensive and have closed structures.To address these limitations,we designed a portable microplasma-atomic emission spectroscopy device based on Solution Cathode Glow Discharge(SCGD)technology,a cutting-edge development in the field.By constructing and utilizing this device,students can independently collect emission signals,thereby enhancing their practical skills and deepening their understanding of instrument structure and the principles of atomic emission spectroscopy.Furthermore,this experimental approach is not only interesting but also fosters students'innovative thinking and scientific research abilities.Compared to traditional analytical instruments,the improved device is cost-effective and easily adaptable for laboratory teaching,thereby increasing students'engagement and improving overall teaching effectiveness.关键词
