A fast and reliable mass spectrometry-based method has been developed to discriminate the positional isomers of -, - and -CHXCOH (X = F, Cl and Br). This is based on the distinct fragmentation patterns of isomeric ThCl(CHXCO) ions generated by electrospray ionization of the solutions with CHXCOH isomers and ThCl. Moreover, the composition of these positional isomers can be conveniently quantified without any pre-treatment according to the proportion of gas-phase fragmentation products.
已经开发出一种快速可靠的基于质谱的方法来区分 -, - 和 -CHXCOH（X = F，Cl 和 Br）的位置异构体。这是基于通过电喷雾将 CHXCOH 异构体和 ThCl 的溶液电离产生的异构体 ThCl(CHXCO)离子的不同碎裂模式。此外，根据气相碎裂产物的比例，可以方便地对这些位置异构体的组成进行定量，而无需任何预处理。
