Abstract

SE DESCRIBE UNA SONDA POLAROGRAFICA PLANAR PARA LA DETERMINACION DEL VALOR LAMBDA DE MEZCLAS GASEOSAS, EN PARTICULAR GASES DE ESCAPE DE MOTORES DE COMBUSTION INTERNA, ASI COMO UN PROCESO PARA PRODUCIRLA. LA SONDA POLAROGRAFICA PLANAR TIENE UNA CELDA DE BOMBEO A CON ELECTRODOS INTERNOS Y EXTERNOS DE BOMBEO (11 Y 16) DISPUESTOS SOBRE UN ELECTROLITO SOLIDO (14). EL GAS QUE HA DE SER MEDIDO, PUEDE SER SUMINISTRADO AL ELECTRODO DE BOMBEO INTERNO (16) A TRAVES DE UNA BARRERA DE DIFUSION. LA SONDA TIENE ADEMAS DOS PAREDES LATERALES Y UNA CENTRAL. LA BARRERA DE DIFUSION ESTA DISEÑADA COMO UNA CAPA DE DIFUSION (19) QUE CUBRE AL MENOS PARCIALMENTE AL ELECTRODO INTERNO DE BOMBEO (16) Y QUE ESTA EXPUESTA AL GAS A SER MEDIDO AL MENOS POR UNA CARA FRONTAL DE LA SONDA. PARA PRODUCIR UNA SONDA POLAROGRAFICA PLANAR, SE USA UN PANEL IMPRESO MULTIPLE, EN EL QUE LA CAPA DE DIFUSION (19) SE APLICA DE TAL MODO QUE SE SUPERPONGA AL MENOS AL BORDE FRONTAL DEL PANEL IMPRESO MULTIPLE, Y CUANDO LOS PANELES IMPRESOS INDIVIDUALES SON LIBERADOS, QUEDA EXPUESTA LA CAPA DE DIFUSION.
