Description
· High Performance Liquid Chromatography (HPLC) Method for Analysis of Triethanolamine
Triethanolamine , also denoted as TEOA , is an organic compound with the chemical formula N(CH2CH2OH)3 . It is primarily used in making surfactants both for industrial and commercial use. It is also found in sunscreen, lotions, liquid detergents, sanitizers, and inks. You can find detailed UV spectra of Triethanolamine and information about its various lambda maxima by visiting the following link.
Triethanolamine can be retained and analyzed using the Primesep 500 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a Ammonium Acetate as a buffer. Detection is performed using ELSF.
