Abstract

UN APARATO Y UN METODO PARA INDUCIR Y DETECTAR FLUORESCENCIA EN UN MEDIO FLUIDO QUE CONTIENE AL MENOS UN FLUOROFOR. EL APARATO COMPRENDE UN EMISOR DE LUZ ADAPTADO PARA EMITIR LUZ DE UNA LONGITUD DE ONDA CAPA DE EXCITAR FLUOROFOROS EN EL MEDIO DE FLUIDO, UN DETECTOR DE LUZ ADAPTADO PARA DETECTAR FLUORESCENCIA EMITIDA POR LOS FLUOROFOROS EXCITADOS POR LA LUZ DE EXCITACION, UN CUERPO DETECTOR, QUE ES PREFERENTEMENTE SOLIDO Y HECHO DE CUARZO, QUE TIENE PARTE DE PARED INTERNAMENTE REFLECTANTES CAPACES DE REFLEJAR AL MENOS LUZ QUE TIENE UNA LONGITUD DE ONDA CORRESPONDIENTE A LA LONGITUD DE ONDA DE LA FLUORESCENCIA Y QUE TIENE UNA CARA DETECTORA ADAPTADA PARA SER EXPUESTA AL MEDIO DE FLUIDO, ADAPTANDOSE EL CUERPO DETECTOR PARA RECIBIR LA LUZ DE EXCITACION DEL EMISOR DE LUZ, COMO POR UNA FIBRA OPTICA, Y PARA TRANSMITIR LA LUZ DE EXCITACION RECIBIDA DENTRO DEL MEDIO DE FLUIDO A TRAVES DE LA CARA DETECTORA, PARA RECIBIR A TRAVES DE LA CARA DETECTORA, LA FLUORESCENCIA EMITIDA POR LOS FLUOROFOROS EXCITADOS EN EL MEDIO DE FLUIDO, Y PARA TRANSMITIR AL MENOS PARTE DE LA FLUORESCENCIA RECIBIDA AL DETECTOR DE LUZ, ESTANDO TANTO EL EMISOR DE LUZ COMO EL DETECTOR POSICIONADOS EN UNA DISTANCIA DESDE LA CARA DETECTORA, Y ESTANDO EL POSICIONADO RELATIVO DEL MISOR DE LUZ, EL DETECTOR OPTICO, Y LA CARA DETECTORA DE MODO QUE EL DETECTOR ES CAPAZ DE RECIBIR LUZ TRANSMITIDA DESDE AL MENOS UNA PARTE DE ESTA PARTE DE LA CARA DETECTORA QUE RECIBE LUZ DESDE EL EMISOR DE LUZ. EL APARATO ES ESPECIALMENTE APROPIADO PARA SU FUNCIONAMIENTO EN MEDIOS TURBIOS O ALTAMENTE TURBIOS COMO UN DEPOSITO DE FERMENTACION O UN AGUA RESIDUAL EN UNA PLANTA PURIFICADORA DE AGUA RESIDUAL.
