Abstract

sistema e método. [001] trata-se de um sistema que compreende pelo menos uma fonte para irradiar radiação eletromagnética em um fluido amostral e um fluido de referência resultando em uma alteração em uma temperatura do fluido amostrai e em uma alteração em uma temperatura do fluido de referência, e um subsistema de processamento que monitora e determina uma concentração de um gás de interesse dissolvido no fluido amostral com base em uma diferença entre a alteração na temperatura do fluido amostral e a alteração na temperatura do fluido de referência, em que o fluido de referência não contém o gás de interesse, e a radiação eletromagnética tem uma faixa de comprimento de onda correspondente a uma faixa de absorção espectral do gás de interesse.
