Determination of Ethanolamines in water as per ASTM D-7599 by LCMS-8045

User Benefits

- Highly sensitive LC-MS/MS method for the determination of four ethanolamines in water with surrogate standard. - Better chromatographic separation with lower concentration of buffer.

Introduction

Overview: Monoethanolamine is bifunctional, and it contains both a primary amine and a primary alcohol. Monoethanolamine is produced by reacting ethylene oxide with ammonia. Further, the reaction also produces ethanolamines such as diethanolamine and triethanolamine. Ethanolamines is a colorless, flammable, viscous liquid with an ammonia-like odor. Ethanolamines are generally used in various fields such as adsorbents for various acid gases, metal corrosion inhibitors, pesticide solvents, pharmaceuticals, cosmetics, and surfactants. However, because ethanolamines have the property of forming carcinogenic nitrosamines, the European Commission prohibits the use of diethanolamine in cosmetics to reduce environmental contamination. In the ASTM standard, an analysis method for ethanolamines, containing diethanolamine, triethanolamine, N-methyldiethanolamine and N-ethyldiethanolamine, has been announced due to concerns about environmental pollution. This method was developed to determine ethanolamines in surface water by direct injection using Shimadzu liquid chromatography mass spectrometer LCMS-8045. These analytes are qualitatively and quantitatively determined by this test method with high sensitivity. The method conforms to the ASTM-D7599, and diethnolamine-D8 was used for the analysis as surrogate to ensure high recovery rate for all the samples tested. All glassware were properly washed with hot water and solvent to ensure reduced interference.
