Abstract

EN UN ESPECTROFOTOMETRO (1) PARA MEDIR LA CONCENTRACION DE UNA SUSTANCIA ESPECIFICA, COMPRENDIENDO DICHO ESPECTROFOTOMETRO UNA FUENTE DE PULSATORIA DE RADIACION (4) EL CUAL ELEVA A UN COMPONENTE DE CORRIENTE ALTERNA UAC, UN COMPONENTE DE CORRIENTE DIRECTA UDC Y UN COMPONENTE DE SEÑAL OSCURA UO EN UNA SEÑAL DE MEDICION, E TIEMPO DE RESPUESTA PARA CAMBIOS EN LA CONCENTRACION DE LA SUSTANCIA ESPECIFICA SE REDUCE MIENTRAS QUE LA RELACION SEÑAL/RUIDO DE LA SEÑAL DE MEDICION MEJORA SIMULTANEAMENTE CUANDO LA FRECUENCIA DE IMPULSO SE DE 50 A 1000 HZ, Y EL COMPONENTE DE CORRIENTE DIRECTA UMEASDC EN LA SEÑAL DE MEDICION SE FILTRA PARA LA NORMALIZACION POR UNA SEÑAL DE REFERENCIA EN UN ANALIZADOR DE SEÑAL (3) CON LO QUE LA CONCENTRACION DE LA SUSTANCIA ESPECIFICA PUEDE SER CALCULADA.
