This review
article discussed application of ionic liquids as matrices (ILMs) for mass
spectrometry (MS). ILMs were applied for matrix assisted laser
desorption/ionization, matrices assisted electrospray ionization (ILMs-ESI-MS)
and desorption corona beam ionization (DCBI-MS).
Ionic
liquids matrices provided several advantages such as low vapor pressure,
have high stability for storage and under vacuum, extremely high sensitivity
and showed low background or interferences.
They are
non-explosive, non-flammable and are thermally stable. The materials are
promising for real measurements and require further investigations to improve
the current performance.
