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.
电喷雾电离（ESI）可将溶液中的分析物转化为气相完整离子，从而进行质谱研究。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），而带电残基模型（CRM）适用于大的球状物质。无序聚合物则提出了链逐出模型（CEM）。
