Abstract

Un método y un aparato para detectar una composicion en un penacho de descarga incluye una fuente de luz que irradia un haz de luz infrarroja quetiene multiples longitudes de onda predeterminadas. Una primera longitud de ondapredeterminada está asociada con el dioxido de carbono y una segundalongitud de onda predeterminada está asociada con un segundo gas, como, por ejemplo, hidrocarburos o monoxidos de carbono. El aparato también incluye unacantidad detectora quedetecta el haz q ue pasa a través del penacho. El aparato calcula una relacion del segundo gas con respecto al dioxido de carbono,basándose en la primera y la segunda longitud de onda detectadas, y esta relacion se multiplica luego por unaconcentracion estima da de dioxido decarbono en el penacho.
