利用Au-400(4+)初级离子产生大的分子离子产率,一些超过1,具有最小的表面损伤。一个令人惊讶的观察是发生的Au-分析物加合物的喷出物的一部分,由一个单一的Au-集群的影响解吸。我们提出的数据表明,Au和Au加合物作为二次离子(例如,AuCN-、AuGly(-)和AuCsI-)是单个一次离子Au-400(4+)与目标原子相互作用的结果。(c)2006 Elsevier B. V.保留所有权利。
Utilizing Au-400(4+) primary ions produces large molecular ion yields, some in excess of unity, with minimal surface damage. A surprising observation is the occurrence of Au-analyte adducts as part of the ejecta desorbed by a single Au-cluster impact. We present data that demonstrate that Au and Au-adducts as secondary ions (e.g., AuCN-, AuGly(-) and AuCsI-) are the result of the interaction between a single primary ion, Au-400(4+) and the target atoms.
