US09123523B2 Excitation of reagent molecules withn a rf confined ion guide or ion trap to perform ion molecule, ion radical or ion-ion interaction experiments 有权
激发具有rf限制离子导向器或离子阱的试剂分子进行离子分子，离子自由基或离子相互作用实验

Excitation of reagent molecules withn a rf confined ion guide or ion trap to perform ion molecule, ion radical or ion-ion interaction experiments
Abstract:
A mass spectrometer is disclosed comprising an RF ion guide or ion trap and a device arranged and adapted to supply a reagent gas within the RF ion guide or ion trap. The mass spectrometer further comprises a photo-ionization device and a control system arranged and adapted: (i) to cause first ions to fragment or dissociate within the RF ion guide or ion trap to form second ions and neutral molecules; and (ii) to cause the photo-ionization device to photo-ionize and/or photo-excite the reagent gas to form reagent ions, excited species or radical species. The reagent ions, excited species or radical species interact with at least some of the neutral molecules located within the RF ion guide or ion trap to form analyte ions.
Abstract(Chinese):

公开了一种质谱仪，其包括RF离子导向器或离子阱，以及布置并适于在RF离子导向器或离子阱内提供反应气体的装置。 质谱仪还包括光电离装置和控制系统，其布置和适应：（i）使第一离子在RF离子导向器或离子阱内分裂或解离以形成第二离子和中性分子; 和（ii）使光电离装置光电离和/或光激发反应气体以形成试剂离子，激发物质或自由基物质。 试剂离子，激发的物质或自由基物质与位于RF离子导向器或离子阱内的至少一些中性分子相互作用以形成分析物离子。
