The desorption and ionization of analytes directly from surfaces or natural matrices under ambient conditions has greatly simplified chemical analysis by mass spectrometry. Among the currently available set of such techniques, easy ambient sonic-spray ionization (EASI) is one of the simplest and most easily implemented. Fuels are among the most important and most complex classes of chemical mixtures and a challenge for fast and comprehensive chemical analysis. This review summarizes the applications of EASI-MS for fast, simple and nearly sample-preparation-free analysis of various fuels, focusing in typification, adulteration and quality control.
在环境条件下直接从表面或天然基质中解吸和离子化分析物，极大地简化了质谱分析化学。在当前可用的此类技术中，简单环境超声喷雾电离（EASI）是最简单和最容易实现的技术之一。燃料是最重要和最复杂的化学混合物之一，也是快速和全面化学分析的挑战。本文综述了 EASI-MS 在各种燃料的快速、简单和几乎无需样品制备的分析中的应用，重点介绍了燃料的分型、掺假和质量控制。
