Mass spectrometry-based methods for analysis of ionic liquid species
The synthesis and use of ionic liquids (ILs) has increased steadily since their inception, driven by their distinctive useful properties. In cases where they replace harmful volatile organic solvents they are often considered “green” and in cases where they are recyclable, they may be considered sustainable. However, many of the properties—such as low volatility and stability—that make them attractive for applications also make them potential persistent contaminants, should they be released into the environment.
