常压电离质谱分子式：CAS号：性质：通常质谱仪中样品的离子化是在高真空下进行的，如常用的电子电离源(EI)、化学电离源(CI)都要求灯丝发射电子，电子使样品或反应气电离，进而产生样品离子，而灯丝的工作条件必须是高真空。随着科学发展，特别是液相色谱-质谱联用仪(LC/MS)出现以后，要求能在常压下(大气压下)进行电离。具有在常压下进行电离功能的质谱称为常压电离质谱。可以实现常压下电离的方法很多，早期的主要方法是使用63Niβ放射源使反应气(如N2)电离，再经过离子-分子反应过程发生电荷转移使样品离子化，新产生的离子从大气压下的反应室通过针孔漏入质谱计进行质谱分析。近年来，各种新型的常压电离方式相继出现，主要有离子喷雾、电喷雾、大气压化学电离等。
