CAS号:

性质:liquid chromatography-mass spectrometry  高压液相色谱仪通过接口和质谱仪相联结;用作分离分析的仪器,简记作LC/MS。LC/MS都配有计算机,构成LC/MS/DS系统。LC用于分离高沸点或热不稳定的混合物,MS作为检测系统给出每个组分的质谱图,计算机用于调控仪器,记录、存储、处理数据,完成定性、定量分析。在LC/MS联用仪中,由于LC与MS的工作条件不同,必须通过一个接口才能使两者匹配。常用的有热喷雾接口、离子束接口、离子喷雾或称电喷雾接口等。接口的作用,是将液相色谱柱流出的洗脱液(含有溶剂和待分析组分)首先雾化,使溶剂蒸发,绝大部分被抽走,仅有待分析组分进入质谱系统,以保证不破坏其高真空度。
