Abstract

Se propone un método para detectar por lo menos un compuesto químico contenido en un medio (312). El método comprende la etapa de verificacion (420) que es usada para determinar si V está contenido en el medio (312). Además el método comprende una etapa de análisis (424) en la que se determina la concentracion c de por lo menos un compuesto químico V. La etapa de verificacion comprende las siguientes sub-etapas: (a1) el medio (312) es expuesto a una primera radiacion de análisis (316) con una longitud de onda lamda variable, la longitud de onda lamda asumiendo por lo menos dos valores diferentes; (a2) por lo menos una funcion de respuesta espectral A(lamda) es generada con la ayuda de la radiacion (324) absorbida y/o emitida y/o reflejada y/o dispersada por el medio (312) en respuesta a la primera radiacion de análisis (316); (a3) por lo menos una funcion de correlacion espectral K (delta lamda) se forma por comparacion espectral de por lo menos una funcion de respuesta espectral A (lamda) con por lo menos una funcion modelo R(lamda + delta lamda), por lo menos la funcion modelo R (lamda) representando una funcion de medicion espectral de un medio (312) que contiene el compuesto químico V y siendo delta lamda una variacion coordinada; (a4) por lo menos una funcion de correlacion espectral K (delta lamda) es examinada en una etapa de reconocimiento de modelo (418), y se llega a una conclusion de si por lo menos un compuesto químico V está contenido en el medio (312); la etapa de análisis (424) comprende las siguientes sub-etapas: (b1) el medio (312) es expuesto a por lo menos una segunda radiacion de análisis (318) teniendo por lo menos una longitud de onda de excitacion lamda EX; (b2) por lo menos una funcion de análisis espectral B (lamdaEX, lamdaRES) es generada con ayuda de la radiacion (326) de la longitud de onda de respuesta lamdaRES absorbida y/o emitida y/o reflejada y/o dispersada por el medio (312) en respuesta a la segunda radicacion de análisis (318) de la longitud de onda lamdaEX y la concentracion c se deduce a partir de esto.
