未来化学侦察兵——质谱仪走进机器人时代

Core Viewpoint - The article discusses the development of an unmanned mass spectrometry robot designed for direct sample analysis in hazardous and radioactive environments, showcasing its capabilities in real-time detection and analysis of various samples [4][7][36]. Research Background and Purpose - Mass spectrometry technology is known for its high sensitivity, specificity, and accuracy, but traditional methods require complex preprocessing and skilled personnel, making it unsuitable for outdoor environments. There is a need for unmanned remote control systems for real-time analysis in dangerous settings [7]. Breakthroughs Achieved - The mass spectrometry robot successfully automates real-time detection of volatile toxic substances and aerosol explosive particles in the air, adapts to complex environments by detecting harmful compounds directly from raw wastewater, and performs chemical analysis of radioactive ore samples on-site [8]. - The robot achieved low detection limits (ng/g or ng/mL, S/N = 3) and a relative standard deviation (RSD < 12.0%, n = 6), validating its remote detection capabilities [8]. Research Methods - The robot utilizes a mini mass spectrometer (8.5 kg), a commercial quadruped robot, and a custom-made sampling device for various sample types [9][10][11]. Experimental Results - The robot successfully detected chemical warfare agents (CWAs) in high-risk air samples, including DMMP, DS, and TEP, confirming its effectiveness in remote applications [28]. - It also identified non-volatile explosives like TNT in aerosol samples and detected highly toxic substances like chlorpyrifos directly from wastewater [29][30]. - The robot performed radiochemical analysis of common and radioactive ores, detecting low background radiation and confirming the presence of radioactive elements [32][34]. Conclusion - The mass spectrometry robot system enables unmanned precise analysis of gas, liquid, and solid samples in hazardous environments, separating humans from high-risk scenarios. Its core advantages include intelligence, safety, and adaptability to multiple matrices, although improvements in environmental tolerance and quantitative analysis capabilities are still needed [36]. Future Prospects - The technology has the potential to replace cumbersome traditional laboratory procedures, with the company focusing on developing portable mass spectrometry systems for real-time chemical analysis applications across various sectors, including public safety and biopharmaceuticals [38].
