Abstract

Un sistema de sensor que elimina las respuestas de un interferente y / o corrige la desviación de la línea base de un sensor para determinar la presencia, concentración o cambio en la concentración de un material objetivo en un ambiente gaseoso. El fluido que fluye hacia el sistema puede ser dirigido por una disposición de válvula a una primera vía de flujo de fluido o una segunda vía de flujo de fluido.
