ICP-MS仪器的过去、现在和未来

摘要

本文从ICP-MS仪器的各个结构组成,介绍了ICP-MS仪器硬件的发展历史和展望,其中重点讨论了ICP-MS进样系统、离子透镜和池技术的发展现状和趋势。越来越多的ICP-MS配置了提升量小、雾化效率高的雾化器,Peltier效应半导体精密控温雾室以及可拆卸式的炬管,而直角偏转的离子透镜也逐渐成为潮流,这些因素提高了ICP-MS在分析高盐样品时的长期稳定性的同时,降低了仪器维护的频率和难度。%Inductively Coupled Plasma Mass Spectrometer hardware history and prospect are introduced based on its framework.Current situation and developing trend of ICP-MS sample introduction system,ion lens and cell technology are the main points to discuss.More and more ICP-MS equip with low uptake,high efficiency nebulizer,Peltier effect temperature precisely controlled chamber and detachable torch,and prevailing right angle defection ion lens,all these factors improve the long term stability for high total dissolved salt samples,and lower the frequency and difficulty of maintenance.
