Abstract

"MéTODO DE DETERMINAçãO DA QUANTIDADE DE INJEçãO DE GáS NA ANáLISE DE ISóTOPOS DE GASES E APARELHO DE ANáLISE E MEDIçãO DE ISóTOPOS DE GASES". Como processamento prévio de medição no qual gás a ser medido que contém, como componentes do gás, dióxido de carbono ¬ 13¬CO~ 2~ e dióxido de carbono ¬ 12¬C0~ 2~ é introduzido em uma célula e no qual são medidas as intensidades de luzes transmitidas com comprimentos de onda adequados para medição dos respectivos componentes do gás, e em seguida os dados são processados para medir as concentrações dos componentes do gás, o ar que possui um volume predeterminado Va é aspirado por um dispositivo de injeção de ar 21, uma válvula de exaustão de gás V6 de uma célula 11 é fechada e o ar armazenado no dispositivo de injeção de gás 21 é transferido para a célula 11 preenchida com o ar a uma pressão atmosférica, para deste modo pressurizar o interior da célula. A pressão pressurizada deste modo é medida como P. O volume Vc da célula é subtraído do produto obtido pela multiplicação da soma VO do volume Va e do volume Vc da célula, pela razão PO/P na qual Po é a pressão pretendida do gás a ser medido à qual foi preparada uma curva de calibração para uma análise e medição de isótopos de gases, determinando, portanto, a quantidade instantânea de injeção de gás do dispositivo de injeção de gás 21. Portanto, as variações de concentrações medidas com base nas alterações em pressão atmosférica podem ser corrigidas.
