摘要
对有机硼化合物进行质谱分析,考察不同种类仪器对样品分析的影响,确定使用电喷雾质谱仪效果最好。进一步考察了流动相、正负离子检测模式、离子化试剂及其浓度等因素的影响。实验发现:样品浓度为1×10-4mol/L,使用V(甲醇):V(H2O)=1:1的混合溶剂为流动相,正离子检测,0.1mol/LNa+为离子化试剂条件下可得到满意的谱图。
Characterization for organic boron compounds was studied by mass spectrometry using EI, ESI, MALDI sources and electrospray ionization mass spectrometry （ESI-MS） was eventually choosed for the analy- sis of these compounds. Several factors including mobile phase, detection mode, cationization reagent and compounds concentration, were investigated. The optimal experimental condition of mass spectrometry for the analysis of organic boron compounds was given.
