摘要：

介绍了教学质谱仪的设计理念及仪器基本构造。教学质谱仪按模块化设计，由进样系统、离子源、质量分析器、检测器、真空系统、控制系统，以及计算机系统等部分组成，适合学生自主搭建与调试。以“教学质谱仪的搭建、调试与应用”实验为例，介绍教学质谱仪在实验教学中的应用。通过自主搭建和调试质谱仪器，不仅可以深化学生对质谱仪器原理和构造、质谱分析方法的认识，提升实践能力和知识综合应用能力，更重要的是打破了学生对科学仪器的神秘感，激发了学生的学习兴趣与好奇心，对培养学生的实践能力和创新意识具有重要影响。

Abstract:

The design concept and basic structure of a teaching mass spectrometer are introduced. The mass spectrometer is modular and comprises a sample input system, an ion source, a mass analyzer, a detector, a vacuum system, a control system, and a computer system. Therefore, students can independently assemble and adjust the mass spectrometer. Considering the "Construction, debugging, and application of a teaching mass spectrometer" experiment as an example, the application of the teaching mass spectrometer in experimental teaching is introduced. By independently assembling the instrument, students should become intimately familiar with mass spectrometers. In addition, students should gain a thorough understanding of mass spectrometry and instrument structure, thereby improving their practical skills and knowledge.

Key words: Teaching mass spectrometer, Modularity, Construction, Debugging, Application
