Abstract

A number of possible ultraviolet MALDI ionization mechanisms based on different fundamental phenomena have been proposed. Recently, it has been argued, based on 'temperature'-selected spectra, that photoionization models should be rejected in favor of thermal ones. Here, one non-thermal photoionization model, the coupled photophysical and chemical dynamics model, is shown to be fully consistent with the data.

摘要

已经提出了一些基于不同基本现象的可能的紫外线 MALDI 电离机制。最近,有人提出,基于“温度”选择的光谱,应该拒绝光致电离模型,转而支持热模型。在这里,一个非热光致电离模型,即耦合光物理和化学动力学模型,被证明与数据完全一致。
