Abstract
METODO Y DISPOSITIVO PARA MEDIR LA CONCENTRACION DE AMONIO TOTAL EN MEDIO LIQUIDO, EN EL QUE SE HACE PASAR POR UNA MEMBRANA SEMIPERMEABLE (12) UNA MEZCLA DE DISOLUCION DE SOSA CAUSTICA Y DE UNA MUESTRA DE LIQUIDO, ASI COMO UN TAMPON ORGANICO, DE MODO QUE SE DESPRENDE GAS AMONIACO QUE AL ATRAVESAR LA MEMBRANA SEMIPERMEABLE ES CONVERTIDO EN UN COMPUESTO ORGANICO DE AMONIO, EL CUAL SE HACE PASAR POR UN ELECTRODO (13) SENSIBLE AL ION AMONIO, QUE GENERA UN POTENCIAL PROPORCIONAL A LA CONCENTRACION DE IONES AMONIO PRESENTES, COMPARANDOSE DICHO POTENCIAL CON EL QUE SE OBTIENE DE UN ELECTRODO DE REFERENCIA (14). EL DIFERENCIAL DE POTENCIAL MEDIDO ENTRE AMBOS ELECTRODOS ES AMPLIFICADO Y CONVERTIDO EN UNA SEÑAL ELECTRICA, QUE ES CONVENIENTEMENTE MODIFICADA PARA SU VISUALIZACION. EL DISPOSITIVO COMPRENDE ADEMAS UNOS MEDIOS (8) DE IMPULSION, UNOS MEDIOS ELECTRONICOS DE TRATAMIENTO DE LA SEÑAL ELECTRICA; Y UNOS MEDIOS DE REPRESENTACION DE LA SEÑAL TRATADA.
