The aerosol mass spectrometer (AMS) is a powerful instrument used to analyze the chemical composition of aerosol particles in the atmosphere. It is capable of detecting and quantifying a wide range of particles, providing valuable insights into air quality, pollution, and climate change. The AMS works by first vaporizing the aerosol particles and then ionizing them to create mass spectra, which can be used to identify the individual chemical components present. Its high sensitivity and ability to perform real-time measurements make the AMS an essential tool for atmospheric research and environmental monitoring. Researchers worldwide rely on the data collected by AMS to understand the sources and behavior of aerosol particles, leading to important advancements in our understanding of air pollution and its impacts.

气相色谱-质谱联用仪分子式:CAS号:性质:气相色谱仪和质谱仪联机(或通过接口),用分离分析的仪器,GC/MS都配有电子计算机,构成GC/MS/DS系统。GC用于混合试样各组分的分离。分离后的单一组分依次进入质谱系统:先经离子源将试样分子离子化,再经质量分析器将离子按质荷比m/z大小分离,顺序由检测器检测构成质谱信号。电子计算机则用作数据的采集、存储、处理、检索和仪器的自动调近代。在GC/MS联用仪中,为了不破坏质谱系统的高真空条件,以保证色谱仪和质谱仪间的匹配,必须采用适当的接口装置以排除色谱的载气,最常用的是分子分离器。若气相色谱中配用内径小于0.25mm的毛细管柱,则可直接与离子源连接,不必通过分离器。是鉴定复杂有机混合物的非常有效的工具。
