Abstract

Esta solicitud se refiere a un método y un aparato para análisis de gases; un aparato (200) puede tener un primer reflector (103) y un segundo reflector (104) situados en cualquiera de los lados de un volumen de muestra (202) para una muestra de gas; la configuración del primer reflector puede ser variable entre por lo menos primera (103) y segunda (103a) configuraciones, en donde cada una de la primera y la segunda configuraciones está dispuesta de tal manera que un haz de radiación óptica procedente de un origen de haz óptico (210) se dirige a una ubicación de detector (212) a través del volumen de muestra; en la segunda configuración, el haz de radiación óptica se refleja por lo menos una vez desde cada uno de dichos primero y segundo reflectores, y la longitud de trayectoria del haz de radiación óptica a través del volumen de muestra es mayor que en la primera configuración.
