Abstract

A detailed procedure for performing surface-induced dissociation (SID) of ions in a dual-cell Fourier transform mass spectrometer is described. It is shown that the technique is applicable to both electron ionization and laser desorption measurements. SID spectra of perfluorotri-n-butylamine, anthracene, (5,10,15,20-tetraphenyl-21H,23H-prophinato)-iron(III) chloride, and [5,10,15,20-tetrakis(2,6-dibromo-phenyl)-21H,23H-prophina to]iron(III) chloride are presented. Conversion efficiencies of molecular ions between 1% and 30% are obtained. It is concluded the method holds promise for dissociation of high mass laser-desorbed ions.

摘要

描述了一种在双池傅里叶变换质谱仪中对离子进行表面诱导解离(SID)的详细程序。结果表明,该技术适用于电子电离和激光解吸测量。给出了全氟三正丁胺、蒽、(5,10,15,20-四苯基-21H,23H-卟吩inato)氯化铁(III)和[5,10,15,20-四(2,6-二溴苯基)-21H,23H-卟吩inato]氯化铁(III)的SID光谱。获得了1%至30%的分子离子转换效率。得出结论,该方法有望用于高质量激光解吸离子的解离。
