Abstract

sistema de medição de gás para medir a presença de um gás predeterminado. a presente invenção se refere a um sistema de medição de gás para medir a presença de um gás predeterminado incluindo uma fonte de luz e um receptor de luz separados por um volume de gás, a fonte de luz emitindo luz em uma faixa escolhida de comprimentos de onda incluindo comprimentos de onda de absorção de característica do gás a ser medido e o receptor de luz sendo capaz de detectar luz na dita faixa do comprimento de onda e o sistema incluindo um analisador de espectro e um meio de armazenamento para armazenar os comprimentos de onda de absorção específicos do gás para, assim, reconhecer uma absorção de gás nos ditos comprimentos de onda específicos. o meio de armazenamento também inclui comprimentos de onda de absorção específicos que distinguem pelo menos um outro material que tem comprimentos de onda de absorção que sobrepõem parcialmente os comprimentos de onda de absorção do dito gás e, assim, detectam o material no volume. o sistema inclui uma unidade analisadora que é adaptada para detectar o dito outro material a partir das medições de gás para distinguir entre o dito material e o gás no volume, e para prover uma medição do dito gás.
