According to the application, a novel derivative compound is formed from a compound that can react by substitution with diethanolamine. Subsequently, the content of the novel compound is measured by means of ultraviolet spectrometry using the absorbance spectrum of the compound which is measured in a wavelength range included between 200 nm and 350 nm. The content of said novel compound is then converted to the original diethanolamine content.

Selon l'application, on forme, à partir d'un composé apte à réagir par substitution avec la diéthanolamine, un nouveau composé dérivé dont la teneur est ensuite mesurée par spectrométrie ultraviolette, à partir du spectre d'absorbance de celui-ci mesuré dans une gamme de longueurs d'onde comprise entre 200 nm et 350 nm, et l'on convertit la teneur de ce nouveau composé en la teneur d'origine en diéthanolamine.
