This review article discussed application of ionic liquids as matrices (ILMs) for mass spectrometry (MS). ILMs were applied for matrix assisted laser desorption/ionization, (ILMALDI-MS), 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. The combination between the conventional matrices and organic bases leaded to high ionization performance. The proton transfer efficiency of ILMs is higher than conventional matrices as the proton take place from the salt form. They were applied for many analytes such as biomarker, protein, peptides, polymers (synthetic and nature), small organic compounds and pharmaceuticals drugs.
