使用电子轰击离子化方法研究氨基糖甙类是不理想的。本文报道用场解吸(简称FD)技术获得的十一个氨基糖甙类的谱图。结果表明谱图不仅给出强的M+H峰,而且还显示出反映氨基糖甙序列的特征碎片。本文还讨论了它们的裂解特点和获得谱图的有关实验技术。
The use of electron impact ionization to study aminoglycosides is undesirable. This article reports the spectrum of eleven aminoglycosides obtained by field desorption (referred to as FD) technique. The results show that the spectrum not only gives a strong M + H peak, but also shows characteristic fragments that reflect aminoglycoside sequences. This article also discusses the characteristics of their cleavage and related experimental techniques for obtaining spectra.
