电喷雾电离(ESI)从溶液中的分析物产生完整的气相离子,用于质谱研究。ESI可以通过不同的机制进行。低分子量分析物遵循离子蒸发模型(IEM),而带电残留物模型(CRM)适用于大的球状物质。提出了一种适用于无序聚合物的链喷射模型。
Electrospray ionization (ESI) generates intact gas-phase ions from analytes in solution for mass spectrometric investigations. ESI can proceed via different mechanisms. Low molecular weight analytes follow the ion evaporation model (IEM), whereas the charged residue model (CRM) applies to large globular species. A chain ejection model (CEM) has been proposed for disordered polymers.
