Title
(EN) MEASURING ANALYTES FROM AN ELECTROMAGNETIC SPECTRUM USING A WAVELENGTH ROUTER
(FR) MESURE D'ANALYTES A PARTIR D'UN SPECTRE ELECTROMAGNETIQUE AU MOYEN D'UN ROUTEUR DE LONGUEURS D'ONDE
Abstract
(EN) Weak signals scattered from analytes at multiple wavelengths can be summed to illuminate either a single detector or a multiplicity of detectors, offering the possibility of concentrating the spectral energy on a smaller total detector area. In addition, a method is disclosed whereby a calibration of the resulting signal for a given analyte can be obtained by means of measuring the quantity of water in the sample volume and by means of measuring the salinity of the fluid in the sample volume.
(FR) Selon l'invention, des signaux faibles diffusés à partir d'analytes à de multiples longueurs d'onde peuvent être additionnés pour éclairer un détecteur simple ou plusieurs détecteurs, offrant ainsi la possibilité de concentrer l'énergie spectrale sur une plus petite surface totale de détection. En outre, l'invention concerne un procédé qui permet d'étalonner le signal résultant d'un analyte donné par la mesure de la quantité d'eau dans le volume échantillon et de la salinité du fluide dans ledit volume échantillon.
