摘要: 本文研究游离胆汁酸及其丁二酸衍生物的快速原子轰击(FAB)质谱.用甘油或硫甘醇作样品的基质,具有不同的灵敏度增强效应。FAB负离子质谱,获得[M-n]-典型离子簇,[M-1]-作为最强离子是每一个样品的基峰.

Abstract: The fast atom bombardment (FAB) mass spectra of free bile acids and their succinyl derivatives are described. Using glycerol or thioglycol as "matrix compatible solvent" of the samples studied, it is noted that various matrix is different in enhanced sensitivity. In FABnegative ion mass spectra the typical (M- n)- cluster ion is observed and the (M- 1)- ion shown as its highest intensity is the base peak for each of the samples.
