Abstract

UN DISPOSITIVO DETECTOR PARA HIDROCARBUROS GASEOSOS COMPRENDE DOS ELEMENTOS SENSIBLES BASADO EN OXIDO SEMICONDUCTOR, UNO DE LOS CUALES ES UN ELEMENTO DE REFERENCIA SENSIBLE, Y EL OTRO ES UN ELEMENTO DE MEDICION SENSIBLE, ESTANDO ESTE ULTIMO CUBIERTO CON UNA CAPA DE MATERIAL POROSO ELECTRICAMENTE AISLANTE QUE CONTIENE UN METAL NOBLE. LOS DOS ELEMENTOS SENSIBLES ESTAN FORMADOS POR UN PROCESO DE PANTALLA DE SEDA, ESTAN CONECTADOS A UN SISTEMA DE COMPARACION DE SEÑAL ELECTRICA, Y SE MANTIENEN A DIFERENTES TEMPERATURAS CUANDO FUNCIONA. EL DETECTOR TIENE SELECTIVIDAD MEJORADA EN LA DETERMINACION DE HIDROCARBUROS GASEOSOS, EN PARTICULAR METANO, INCLUSO SI ALTAS CONCENTRACIONES DE GASES DE INTERFERENCIA TALES COMO EL ETANOL ESTAN PRESENTES.
