用电喷雾电离质谱仪研究了DOTA在水溶液中对钚(III)、Am(III)的络合作用。至于Eu(III)的络合作用，数据表明在负离子模式下存在一个极其稳定的离子ML-。用源内和离子内陷阱碰撞引起的La(III)和An(III)物种的离解研究了气相离子的动力学稳定性，为该体系提供了有价值的信息。
Electrospray ionization mass spectrometry was used to investigate the complexation of plutonium(III) and americium(III) by DOTA in aqueous solution. As for europium(III) complexation, data obtained show the presence of a single extremely stable ion ML- in negative ion mode. The kinetic stability of gas phase ions has been investigated by both in-source and in-ion trap collision induced dissociation for lanthanides(III) and actinides(III) species and provides valuable information on the system.
