Abstract: Virtual simulation experiments represent an emerging trend in the pedagogical approach to teaching large-scale instrument analysis, effectively integrating virtual simulation technology with hands-on instrument training to maximize students' comprehensive application skills in large-scale instrument analysis. This paper focuses on a virtual simulation system for laser-induced breakdown spectroscopy (LIBS), meticulously simulating the entire LIBS experimental procedure, including sample preparation, spectrum acquisition, qualitative and quantitative analysis. Through a blended learning model that combines virtual and physical experiments, the process facilitates real-time monitoring and comprehensive assessment of student performance. This approach not only enhances students' independent inquiry ability and innovative consciousness, but also aims to cultivate top-notch talents with independent thinking and practical abilities.

Key words: Virtual simulation experiment, Laser-induced breakdown spectroscopy, Instrumental analysis experiment, Autonomy, Creativity
