The liquid secondary ionization mass spectrometry of oligosaccharide anions is investigated with an external source quadrupole Fourier transform mass spectrometer (FTMS). Selected linear and cyclic oligosaccharides are analyzed to determine the performance of the external source FTMS in the anion mode. Fragmentation behavior of disaccharides is characterized and related to the fragmentation behavior of larger oligomers. General correlation is found between the linkages and the fragment ions observed.
使用外源性四极杆傅里叶变换质谱仪（FTMS）研究了寡糖阴离子的液体二次离子质谱。分析了选定的线性和环状寡糖，以确定外源性FTMS在负离子模式下的性能。对二糖的碎裂行为进行了表征，并将其与较大寡聚物的碎裂行为相关联。发现观察到的键合与碎片离子之间存在一般相关性。
