HPLC ELSD Method for Analysis of Triethanolamine on Primesep 500 Column

HPLC Method for Triethanolamine on Primesep 500 by SIELC Technologies

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.

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 sulfuric acid as a buffer. Detection is performed using UV.
