In mass spectrometry, analytes must be released in the gas phase. There are two representative methods for the gasification of the condensed samples, , ablation and desorption. While ablation is based on the explosion induced by the energy accumulated in the condensed matrix, desorption is a single molecular process taking place on the surface. In this paper, desorption methods for mass spectrometry developed in our laboratory: flash heating/rapid cooling, Leidenfrost phenomenon-assisted thermal desorption (LPTD), solid/solid friction, liquid/solid friction, electrospray droplet impact (EDI) ionization/desorption, and probe electrospray ionization (PESI), will be described. All the methods are concerned with the surface and interface phenomena. The concept of how to desorb less-volatility compounds from the surface will be discussed.
在质谱分析中，分析物必须以气相形式释放。对于凝聚态样品的气化，有两种具有代表性的方法，即烧蚀和解吸。烧蚀基于凝聚态基质中积累的能量引发的爆炸，而解吸是发生在表面的单分子过程。本文将介绍我们实验室开发的用于质谱分析的解吸方法：快速加热/快速冷却、莱顿弗罗斯特现象辅助热解吸（LPTD）、固/固摩擦、液/固摩擦、电喷雾液滴撞击（EDI）电离/解吸以及探针电喷雾电离（PESI）。所有这些方法都涉及表面和界面现象。将讨论如何从表面解吸低挥发性化合物的概念。
