Abstract

UN METODO Y APARATO PARA ACTIVAR Y MEDIR UN FENOMENO ELECTROQUIMIOLUMINISCENTE UTILIZANDO UNA FORMA DE ONDA DE TENSION APLICADA AL ELECTRODO DE TRABAJO VOLTAMETRICO QUE MEJORA LA PRECISION Y EXACTITUD DE LAS MEDICIONES. ESTA FORMA DE ONDA TIENE UNA VELOCIDAD DE EXPLORACION EN EL RADIO DE ACCION DE TENSIONES POR LAS CUALES SE ACTIVA LA ELECTROQUIMIOLUMINISCENCIA Y EN ESTE RADIO DE ACCION ES SUSTANCIALMENTE DE DE FORMA SINUIDAL. LA FORMA DE GUIA ES UN RESULTADO DE LA LOCALIZACION DEL ELECTRODO DE REFERENCIA (20) DE UN POTENCIOSTATO EN PROXIMIDAD POTENCIAL PROXIMA A SU ELECTRODO CONTADOR (16), Y DE LA APLICACION DE UNA FORMA DE ONDA DE TENSION DE EXPLORACION UNIFORME AL ELECTRODO DE REFERENCIA (20). LA FORMA DE ONDA SE PUEDE SINTETIZAR DIGITALMENTE, CONVERTIRSE EN FORMA ANALOGA, Y APLICARSE DIRECTAMENTE AL ELECTRODO DE TRABAJO (18) CON EL ELECTRODO DE REFERENCIA (20) EN PROXIMIDAD POTENCIAL CERCANA AL ELECTRODO DE TRABAJO (18).
