For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. This analysis was done with the mobile phase made of 20% acetonitrile and 80% water.

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. 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.

HPLC Separation of Ethanolamines (Monoethanolamine, Diethanolamine, and Triethanolamine) Using a Primesep 100 Column
December 5, 2006
Primesep 100 separates ethanolamines (monoethanolamine, diethanolamine, and triethanolamine) by a combination of cation-exchange, hydrophobic, and polar interactions. The separation uses a mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) with evaporative light scattering detection (ELSD).
Application Column
Primesep 100
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
