Abstract

EL DISPOSITIVO PERMITE LA MEDICION SIMULTANEA DE CONCENTRACIONES Y ABSORCIONES DE RADIACION DE MEZCLAS DE VARIOS COMPONENTES CON AYUDA DE DETECTOR DE RADIACION UNICO SITUADO DETRAS DE LA CELULA DE MEDICION, CON UNA EXACTITUD DE MEDICION MUY ELEVADA, UNA ESTABILIDAD A LARGO PLAZO Y BAJOS COSTES. PARA SOLVENTAR LA TAREA SE PROPONE, DE ACUERDO CON EL PROCEDIMIENTO, QUE SEAN EMITIDAS RADIACIONES A TRAVES DEL MEDIO DE DIFERENTE LONGITUD DE ONDA CON DIFERENTE FRECUENCIA DE IMPULSOS Y QUE SE SEPAREN LAS SEÑALES ESPECIFICAS DE MOLECULAS GENERADAS EN EL DETECTOR DE RADIACION MEDIANTE AMPLIFICADORES DE BANDA ESTRECHA DE FRECUENCIAS CENTRALES DIFERENTES. EL DISPOSITIVO ESTA CONFIGURADO DE MODO QUE LA FUENTE DE RADIACION (40) TIENE DISPUESTA POSTERIORMENTE UN SISTEMA CHOPPER (53) DE SISTEMAS PARCIALES ESTACIONARIOS (42, 56, 57) Y SISTEMAS PARCIALES MOVILES (41, 54, 55) Y QUE LAS RADIACIONES (62,63) SEAN SEPARADAS POR LOS AMPLIFICADORES DE BANDA ESTRECHA (48, 49) Y PUEDAN SEGUIR PROCESANDOSE.
