Application of ICP-MS in the Innovation and Practice of Instrument Analysis Course - Taking the Determination of Cesium in Soil as an Example

Abstract

Instrumental analysis is an important part of analytical chemistry, which plays a crucial role in cultivating the experimental operation ability of students in disciplines such as environment, geology, and medicine. Inductively coupled plasma mass spectrometry (ICP-MS) is currently an irreplaceable basic equipment in inorganic element analysis, and incorporating it into experimental teaching content is a requirement of the times. However, there is still a lack of application in this area. This article focuses on the graduate course “Modern Detection Technology”. The experimental course adopts a mixed teaching mode of pre class theoretical guidance and in class emphasis on practical operation. It combines theoretical and practical teaching organically, and takes the current hot topic of radioactive pollution as the problem orientation. The teaching mainly focuses on analyzing experimental design, instrument operation and use, sample measurement and result analysis, etc. The teaching mode and content of ICP-MS continuously explored to improve the quality of experimental teaching and enable students to comprehensively enhance their basic skill knowledge, scientific research literacy, and innovation awareness.
