Abstract

Capteur optique permettant de déterminer le pH indépendamment de la force ionique, et comprenant une composition de polyuréthane, de polyurée-uréthane ou de polyurée solide contenant une fluorescéine sensible au pH liée par l'intermédiaire d'un groupe urée ou uréthane sous forme d'une membrane sur un matériau de support transparent. L'invention se rapporte également à un procédé de fluorescence optique qui permet une détermination du pH d'une précision élevée indépendante de la force ionique de la solution de mesure. Ce procédé convient particulièrement à la détermination du pH de solutions physiologiques, en particulier la détermination du pH du sang.
