What Is ASTM D7599 Ethanolamines Water Liquid Chromatography?
ASTM D7599 describes a standard test method for the determination of ethanolamines—monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA)—in water samples by liquid chromatography (LC). Ethanolamines are widely used industrial chemicals that require monitoring in wastewater, process streams, and environmental samples.
Liquid chromatographic separation provides selective, sensitive detection of individual ethanolamine species in complex aqueous matrices, enabling both compliance monitoring and process control in industries that use or produce these chemicals.

ASTM D7599 Ethanolamines Water Liquid Chromatography FAQs
Ethanolamines (MEA, DEA, TEA) are organic compounds widely used in gas treating, surfactants, cosmetics, and chemical manufacturing. They are moderately toxic to aquatic organisms and require monitoring in wastewater and environmental samples.
LC provides direct separation and quantification of individual ethanolamine species without derivatization steps required by some other methods. It handles the highly polar, water-soluble nature of ethanolamines effectively.
The method can achieve detection limits in the low mg/L to sub-mg/L range, sufficient for most industrial wastewater compliance monitoring requirements.
The method is designed for aqueous environmental and process water samples. High-concentration amine solutions such as gas treatment solvents require significant sample dilution before analysis using this method.
Other amines or organic compounds with similar chromatographic retention times may interfere. Sample preparation steps such as filtration and appropriate column and mobile phase selection minimize these effects.
