Abstract

METODO Y DISPOSITIVO DE MEDICION DE LA CONCENTRACION DE AMONIO TOTAL EN UN MEDIO LIQUIDO, EN EL QUE SE HACE UNA MEZCLA DE UNA DISOLUCION DE UNA SOLUCION DE ALCALINIZACION Y UNA MUESTRA DE FLUIDO PARA PASAR A TRAVES DE UNA MEMBRANA SEMIPERMEABLE (12), ASI COMO UN COMPUESTO TAMPON ORGANICO, DE MANERA QUE LA MEZCLA DESPIDA EL AMONIO EN UNA FASE GASEOSA QUE, AL PASAR A TRAVES DE LA MEMBRANA SEMIPERMEABLE, SE CONVIERTE EN UN COMPUESTO DE AMONIO ORGANICO,. QUE ESTA HECHO PARA PASAR A TRAVES DE UN ELECTRODO (13) SENSIBLE AL ION DE AMONIO, QUE GENERA UN POTENCIAL PROPORCIONAL A LA CONCENTRACION DE IONES DE AMONIO PRESENTES, Y ESTE POTENCIAL SE COMPARA CON EL OBTENIDO A PARTIR DEL ELECTRODO DE REFERENCIA (14). LA DIFERENCIA DE POTENCIAL MEDIDO ENTRE AMBOS ELECTRODOS SE AMPLIFICA Y SE CONVIERTE EN UNA SEÑAL ELECTRICA, QUE SE MODIFICA SUSTANCIALMENTE PARA SU VISION. EL DISPOSITIVO COMPRENDE, ADEMAS MEDIOS DE BOMBEO (8), MEDIOS ELECTRONICOS DE TRATAMIENTO DE L SEÑAL ELECTRICA Y MEDIOS DE REPRESENTACIONDE LA SEÑAL TRATADA.
