Second generation ionic liquid matrices are developed, examined, and tested. They have shown a wide mass detection range (1000 Da to270,000 Da) for proteins and peptides with greater S/N ratios than solid matrices. These ionic liquid matrices also ex

Dynamic solvation of the dye coumarin 153 is studied in a phosphonium ionic liquid: hexadecyltributylphosphonium bromide, [(C4)3C16P+][Br-]. It forms micelles in water, and the bulk also exists as a liquid under our experimental conditions. This syst

Dynamic solvation of the dye, coumarin 153, is compared in an ionic liquid that forms micelles in water against the bulk solvent. This provides the unprecedented opportunity of investigating the behavior of the ionic liquid in two globally different

Four new ionic liquids (IL) were prepared and bonded onto 5-microm silica particles for use as adsorbent in solid-phase microextraction (SPME). Two ILs contained styrene units that allowed for polymerization and higher carbon content of the bonded si
