Core Viewpoint - The research team from Jinan University has developed an intelligent mass spectrometry robot system (MS Robot) that successfully achieves unmanned operation from sample collection to mass spectrometry analysis in hazardous chemical and radioactive environments, demonstrating adaptability to dangerous environments and reliability in on-site analysis [1][3]. Summary by Sections Introduction - The MS Robot system integrates a mini mass spectrometer, quadruped robot, switchable mechanical arm sampler, and direct ionization device, enabling autonomous collection and real-time analysis of various sample forms including gas, liquid, and solid [3][5]. Importance of On-Site Analysis - Timely understanding of the chemical composition of hazardous pollution sources is crucial for human health and ecological safety. Existing analysis methods face challenges in detection capability, safety, portability, and versatility in hazardous environments [5][6]. Performance of MS Robot - The MS Robot system exhibits excellent sensitivity (detection limit at ng/g or ng/mL level, S/N=3) and good reproducibility (RSD < 12.0%, n=6). It has been successfully applied in various complex scenarios for unmanned on-site mass spectrometry analysis [5][6]. Applications in Hazardous Environments - The system has been utilized for remote rapid detection of toxic substances in air, aerosols, wastewater, and radioactive ore samples, showcasing its safety, controllability, applicability, and robustness in hazardous environments [6][13][14]. Technical Construction of MS Robot - The MS Robot system consists of a self-made mechanical arm, mini mass spectrometer, switchable sampler, and biomimetic quadruped robot. It features modular design for sampling different types of samples and employs novel ionization techniques for real-time analysis [10][19]. Rapid Analysis of Toxic Chemicals - The system can detect toxic substances in gas, aerosol, and liquid samples, including chemical warfare agents and pesticides, demonstrating high sensitivity and accuracy in complex sample matrices [13][15]. Analysis of Radioactive Minerals - The MS Robot system effectively identifies radioactive sources and their chemical components in environments like uranium mines, providing reliable data for nuclear material monitoring and environmental radioactive assessment [14][16][19]. Conclusion - The MS Robot innovatively addresses key challenges in unmanned analysis of various sample forms in hazardous environments, enhancing safety and efficiency in on-site environmental analysis.
