A fast and simple method involving separation and determination of thallium (Tl) species, based on novel ionic liquid-assisted ion pairing dispersive liquid-liquid microextraction (DLLME) method, was developed. Initially, Tl(III) was selectively complexed with chloride ion to form [TlCl(4)](-) chlorocomplex. Subsequently

Analysis of Difficult Polar Compounds using Our Ion Pair Reagents and Supelco Ascentis HPLC Columns

Because reversed-phase HPLC is primarily dependent on hydrophobic interactions between the stationary phase and analyte, ion pairing is occasionally necessary to obtain sufficient retention of polar, ionizable compounds.
