Abstract
Green chemistry is a way to avoid threats to human health and the environment in chemical processes, including analytical methodology. According to the 12 principles provided by ACS Green Chemistry Institute, first described by Anastas and Warner, prevention of waste generation should be first considered as an alternative to ways of treating waste. Therefore, analytical techniques that may reduce solvent waste are of great interest towards greener analysis. High-field asymmetric waveform ion mobility spectrometry (FAIMS) utilizes electrical fields to achieve separation, post an ionization source, and could provide an alternative method for separation and reduce solvent use in comparison with traditional HPLC methodologies. In this article, the operational principles and developments of FAIMS will be discussed, including the advantages of adding solvent vapor to the carrier gas. In addition, applications and challenges of implementing FAIMS technology will also be discussed.
