Abstract

Se proporciona un electrodo de referencia el cual esta estable sobre un intervalo amplio de temperaturas, presiones y condiciones quimicas. El electrodo de referencia objetivo de acuerdo con la presente invencion comprende un protector tubular compuesto de cuarzo que tiene un extremo cerrado, distal y un extremo abierto, proximo. Una varilla ceramica aislante se conecta aparentemente a la abertura en el extremo distal cerrado del protector para formar micro-grietas entre la varilla ceramica y el protector de cuarzo (llamada una union agrietada, CJ). La CJ da una trayectoria muy tortuosa para la conduccion de iones desde el interior del electrodo de referencia (RE) a un electrodo de trabajo (WE). Dentro del protector tubular esta un conductor electrico (por ejemplo, un cable de plata) colocado en un electrolito que comprende una mezcla de sales de metal alcalino (por ejemplo, AgCI y KCI), extendido desde el electrolito hacia arriba hasta un medio de sellado en el extremo proximo del protector de cuarzo
