Rapid Characterization of Complex Viscous Liquids at the Molecular Level

摘要

Mass spectrometry (MS) is the method of choice for molecular characterization of complex samples, due to its unparalleled ability to acquire detailed qualitative and quantitative information as well as its exceptional sensitivity and specificity. Recent progress in the rapid characterization of complex samples by MS has mostly been due to the rapid development of ambient ionization techniques, which require no or only minimal sample pretreat-ment. For instance, analytes present on solid surfaces or in liquid solutions, aerosols, and living objects have been successfully detected at low concentration levels. However, studies on viscous complex mixtures remain sparse.
