一般描述

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:

For tetradecyltrimethylammonium bromide in boric acid/borate or acetic acid/acetate buffer and NaCl or CaCl₂ as the added salt, it is investigated whether the retention behaviour of weak acids in MEKC with cationic surfactant can be modelled by assuming for the

The vibrational spectra of platinum nanoparticles (12 nm) capped with tetradecyltrimethylammonium bromide, C(14)TAB, were investigated by Fourier transform infrared (FTIR) spectroscopy. We have shown that the thermal decay of Pt-C(14)TAB nanoparticles in N(2), H(2), and O(2) atmospheres leads to the
