Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA DETERMINAR UN ANALITO CONTENIDO EN UNA MATRIZ DISPERSORA, EN ESPECIAL BIOLOGICA. EN UN PASO DE LA DETERMINACION SE REALIZAN MEDICIONES DE DETECCION, EN LAS CUALES UNA RADIACION LUMINOSA SE DIRIGE A LA MATRIZ (6) COMO LUZ PRIMARIA Y LA RADIACION EMERGENTE DE LA MATRIZ (6) SE DETECTA COMO LUZ SECUNDARIA, CON EL FIN DE DETERMINAR COMO MAGNITUD DE MEDIDA LA PROPIEDAD FISICA MEDIBLE DE LA LUZ QUE VARIA POR LA INTERACCION DE LA LUZ CON LA MATRIZ (6). EN UN PASO DE EVALUACION SE OBTIENE INFORMACION SOBRE LA PRESENCIA DEL ANALITO EN LA MATRIZ (6). LA DETERMINACION DE ANALITOS ABSORBENTES DEBILES DE LA LUZ FRENTE A UN FONDO ABSORBENTE FUERTE PUEDE MEJORARSE SI SE EMPLEAN, COMBINADOS ENTRE SI, DOS PROCEDIMIENTOS DE SELECCION PARA LA RECOGIDA SELECTIVA DE LA LUZ SECUNDARIA. EN EL PRIMERO, LA LUZ PRIMARIA (14) SE ENFOCA MEDIANTE UN ELEMENTO DE ENFOQUE OPTICO (16) SOBRE UN AREA DE FOCO (17) QUE SE ENCUENTRA A UNA PROFUNDIDAD ESPECIFICADA (D) DENTRO DE LA MATRIZ (6) Y EL AREA DE FOCO (17) SE REPRODUCE, MEDIANTE UN ELEMENTO DE ENFOQUE OPTICO (16, 21), EN UNA ABERTURA DE ENTRADA DE LUZ (24) DISPUESTA EN EL CAMINO OPTICO DE LA LUZ SECUNDARIA (19) HACIA EL DETECTOR. EN EL SEGUNDO, UN MEDIO ADICIONAL DE SELECCION DE PROFUNDIDAD, CON PREFERENCIA UN PROCEDIMIENTO DE MEDIDA DE BAJA COHERENCIA, DETECTA COMO LUZ SECUNDARIA LA LUZ REFLEJADA A UNA PROFUNDIDAD DE MEDIDA DEFINIDA, EN QUE LA PROFUNDIDAD DE MEDIDA COINCIDE CON LA PROFUNDIDAD DEL FOCO.
