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:

The phase behavior, rheological properties, and structures of two salt-free catanionic surfactant systems, tetradecyltrimethylammonium hydroxide ((TTA)OH)/lauric acid (LA)/H(2)O and cetyltrimethylammonium hydroxide ((CTA)OH)/LA/H(2)O, in the presence of deoxycholic acid (DeCA) were investigated and compared with the results of cholic acid (CA).

The interaction of the cationic surfactant cetyltrimethylammonium bromide (CTAB) with bovine serum albumin (BSA), a globular protein, has been studied by small-angle neutron scattering (SANS), fluorescence and circular dichroism (CD). SANS measurements show that at low [CTAB] the protein shows

This study aims to understand the underlying reasons for the poor flotation response of marine microalgae. The flotation performance and hydrophobicity of a freshwater microalga (Chlorella sp. BR2) were compared to those of a marine microalga (Tetraselmis sp. M8) at

We report information regarding the structure at the interface between hexadecane and an aqueous solution of trimethyl tetradecyl ammonium bromide (C14TAB) with appropriate deuterium labeling. We also report the role of the headgroup size and the charge on structures at

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
