Ambient Ionization Mass Spectrometry: On-Site Detection of Tainted Chemical Compounds in Foods

摘要

Several novel outlooks and concepts for mass spectrometric ionization have been introduced in the last ten years, some of which have revolutionized the field of mass spectrometry. One of these novelties is known as ambient mass spectrometry (AMS), which is generally defined as "mass spectrometric ionization methods that operate under ambient conditions and require minimal or no sample pretreatment". Ambient MS allows direct, rapid, insitu, real-time, and high-throughput analyses of a wide range of substances from various surfaces and matrices, and drastically improves the capabilities of mass spectrometry. This paper introduces the principle and instrumentation of the ambient ionization techniques which can be used in detecting trace tainted chemical compounds in foods.
