Abstract

PROCEDIMIENTO PARA DETERMINAR UNA SUSTANCIA CONTENIDA EN EL AGUA, EN PARTICULAR EL CONTENIDO DE CARBONO ORGANICO Y/O NITROGENO PARA LO CUAL SE EVAPORA Y CALCINA UNA MUESTRA ACUOSA EN UN RECIPIENTE DE CALENTAMIENTO (154A) DOTADO POR LO MENOS DE UN SISTEMA DE CALEFACCION (154), Y CONDUCIENDO EL PRODUCTO DE LA COMBUSTION EN UNA CORRIENTE DE GAS DE TRANSPORTE A UN DETECTOR (142) PARA DETERMINAR LA CONCENTRACION DE UNA COMBINACION GASEOSA DE LA SUSTANCIA CONTENIDA, PARA LO CUAL EL RECIPIENTE DE CALENTAMIENTO O EL PRIMER RECIPIENTE DE CALENTAMIENTO TIENE EN EL MOMENTO DE LA ALIMENTACION DE LA MUESTRA ACUOSA UNA TEMPERATURA INFERIOR O A LO SUMO DENTRO DE LA GAMA DE LA TEMPERATURA DE EBULLICION DE LA MUESTRA, AUMENTANDOSE LA TEMPERATURA DESPUES DE SU ALIMENTACION, CON LO CUAL LA MAESTRA SE CALIENTA POR ESE MISMO EQUIPO DE CALENTAMIENTO EN UNA PRIMERA FASE DESDE UNA TEMPERATURA INICIAL INFERIOR A LA TEMPERATURA DE EBULLICION HASTA UNA TEMPERATURA DE EVAPORACION, Y EN UNA SEGUNDA FASE, SE CALIENTA AUNA TEMPERATURA CONSIDERABLEMENTE MAS ALTA, MANTENIENDOSE EL PRODUCTO DE COMBUSTION EN UN CIRCUITO QUE ESTA CERRADO DURANTE EL ANALISIS.
