Title (EN) AN OPTICAL PROBE AND METHOD FOR MONITORING AN ANALYTE CONCENTRATION
(FR) SONDE OPTIQUE ET PROCEDE PERMETTANT DE SURVEILLER LA CONCENTRATION D'UN ANALYTE
Abstract: front page image
(EN)An optical probe and a method of monitoring analyte concentration, or the partial pressure of a gas in a sample are described. The optical probe contains at least two luminescent (fluorescent or phosphorescent) molecules whose luminescence is quenched by the analyte being measured. The absorption spectrum of each type of luminescent molecule overlap with the absorption spectrum of each of the other molecules, and the emission spectrum of each molecule overlaps with the emission spectrum of each of the other molecules. The partial pressure of a gas or concentration of an analyte is measured using the quenching of the luminescence of said molecules by the analyte.
(FR)Sonde optique et procédé permettant de surveiller la concentration d'un analyte, ou la pression partielle d'un gaz se trouvant dans un échantillon. La sonde optique renferme au moins deux molécules luminescentes (fluorescentes ou phosphorescentes) dont la luminescence est étouffée par l'analyte dont on mesure la concentration. Le spectre d'absorption de chaque type de molécule luminescente recouvre le spectre d'absorption de chacune des autres molécules, et le spectre d'émission de chaque molécule recouvre le spectre d'émission de chacune des autres molécules. On mesure la pression partielle d'un gaz ou la concentration d'un analyte à l'aide de l'étouffement de la luminescence desdites molécules par l'analyte.
