Electrospray ionization (ESI) and matrix-assisted laser desorption ionization (MALDI) are soft ionization techniques commonly used in mass spectrometry. Although in-source and post-source decays of MALDI have been investigated extensively, the analogous decays of ESI have received little attention. Previous studies regarding the analogous decays of ESI focus on the dissociation of multiply charged proteins and peptides. The decay of carbohydrates in ESI has not been investigated yet, and it may have interference in carbohydrate structural determination.

N-聚糖的电喷雾电离源内衰减及其对N-聚糖结构鉴定的影响

电喷雾电离 (ESI) 和基质辅助激光解吸电离 (MALDI) 是质谱分析中常用的软电离技术。尽管已经广泛研究了 MALDI 的源内和源后衰减，但 ESI 的类似衰减很少受到关注。以前关于 ESI 类似衰减的研究集中在多电荷蛋白质和肽的解离上。尚未研究 ESI 中碳水化合物的衰变，它可能会干扰碳水化合物的结构测定。
