[Contribution to the study of phenothiazine detection by inhibition of phosphorescence in liquid chromatography].
Diacetyl, in deaerated solutions, is a major room temperature phosphorescent compound. Its phosphorescence quenching is proposed in order to quantify results on phenothiazine derivatives. It is established from the luminescent data on phenothiazines that diacetyl phosphorescence can be quenched quantitatively by these compounds. This detection mode is applied to liquid chromatography limitations as well as the mechanism of the quenching are discussed.
