General description
Ion-pairing reagents as mobile phase additives facilitate the separation of ionic and highly polar substances on reversed phase HPLC columns. Their purity is an important parameter for their successful application. Sigma-Aldrich offers an wide range of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) analyzes. All mobile phase additives are subject to rigorous testing with special emphasis on the requirements of modern reversed phase HPLC:

Two fatty acids, perfluorononanoic acid (C(8)F(17)COOH) and nonanoic acid (C(8)H(17)COOH), were mixed with a cationic hydrocarbon surfactant, tetradecyltrimethylammonium hydroxide (TTAOH), in aqueous solutions for comparative investigation. Phase behaviors of the two systems are quite different because of the special properties

Unfolding of rabbit serum albumin (RSA) by cationic surfactants cetyltrimethylammonium bromide (CTAB) and tetradecyltrimethylammonium bromide (TTAB) was studied by exploiting surface tensiometry, small-angle neutron scattering (SANS), intrinsic fluorescence, resonance Rayleigh scattering (RRS) (also referred as turbidity at 350/350), and circular

Keeping in view the use of surfactants in drug delivery, the interactions of surface active ionic liquids, such as 1-tetradecyl-3-methylimidazolium bromide (C(14)mimBr), with drugs, viz., dopamine hydrochloride (DH) and acetylcholine chloride (AC), have been studied, and the results are further
