在化学分析的世界中,ESI-MS是一种关键的仪器,它全称为电喷雾质谱(Electro Spray Ionization-Mass Spectroscopy)。ESI-MS是质谱技术(Mass Spectroscopy,简称MS)的一个分支,质谱作为测定分子质量和进行化合物结构分析的高效工具,其工作原理依赖于精密的设备结构。这个仪器主要由四个核心部分组成:进样系...
MS为MassSpectroscopy的缩写,是质谱的含义,质谱是分子质量精确测定与化合物结构分析的重要工具。质谱仪分为进样系统、离子源、质量分析器和检测器四部分质谱仪啊 ,MS就是指质谱仪,ESI指的是质谱仪轰击分子的方式,具体是那一种记不清楚了用来测纺织品中HBCD含量的你在百度中打出下列文字即可化学仪器E...
