[Objective/Significance] This study aims to analyze the international development trends of mass spectrometers in the nuclear field and offer reference suggestions for the high-quality development of analytical instruments in China. [Method/Process] The research methodology entailed literature and patent searches using the Web of Science Core Collection and the Derwent Innovations Index database. CiteSpace software was employed to analyze 5,531 publications and 350 patents on nuclear mass spectrometers from the past two decades, examining research trends, topics, major countries and institutions, and patent technology hotspots. [Results/Conclusions] The study reveals a consistent annual publication volume for nuclear mass spectrometer research, with a gradual increase in citation frequency. Patent applications show fluctuating patterns with a recent upward trend. The focus of research is on the development and application of instruments, mainly involving accelerator mass spectrometers, secondary ion mass spectrometers, and plasma mass spectrometers. The United States, Japan, Germany, and France are the key research countries, with prominent institutions such as the U.S. Department of Energy and the Swiss Federal Institute of Technology. Patent technology hotspots are in the development of mass spectrometers and their application in the biomedical field. Expert opinions and data analysis suggest a widespread use of mass spectrometer technology in biomedical applications with promising market prospects. The priority for China is the localization of core components for mass spectrometers.
