O analisador de carbono org\u00e2nico total AST-800S \u00e9 um instrumento anal\u00edtico que utiliza o princ\u00edpio da oxida\u00e7\u00e3o catal\u00edtica a alta temperatura - dete\u00e7\u00e3o NDIR para medir a concentra\u00e7\u00e3o de carbono org\u00e2nico total em amostras de \u00e1gua. Pode detetar amostras de \u00e1gua com concentra\u00e7\u00f5es de TOC que variam entre 0,050 ppm e 35.000,0 ppm. Apresenta elevada sensibilidade, exatid\u00e3o e excelente estabilidade.
\n Vis\u00e3o geral do sistema<\/b>
\nO AST-800S \u00e9 um instrumento de estrutura simples. Os seus principais componentes est\u00e3o instalados na unidade principal. Antes da medi\u00e7\u00e3o, o instrumento precisa de ser ligado ao percurso do g\u00e1s e os reagentes devem ser preparados. O instrumento \u00e9 controlado por um software especializado instalado num computador externo para tarefas de processamento de dados, tais como medi\u00e7\u00e3o, calibra\u00e7\u00e3o e impress\u00e3o.<\/p>\n
Princ\u00edpio de funcionamento<\/b>
\nAtrav\u00e9s da utiliza\u00e7\u00e3o de um catalisador de oxida\u00e7\u00e3o de alto desempenho no forno de combust\u00e3o, a amostra \u00e9 totalmente queimada e decomposta a altas temperaturas em di\u00f3xido de carbono e \u00e1gua. O vapor de \u00e1gua passa ent\u00e3o atrav\u00e9s.
\nO condensador \u00e9 arrefecido e depois retirado. O di\u00f3xido de carbono \u00e9 medido utilizando um detetor de infravermelhos n\u00e3o dispersivo (NDIR) para determinar o teor total de carbono (TC) na amostra.
\nO carbono inorg\u00e2nico presente na amostra \u00e9 decomposto em di\u00f3xido de carbono e \u00e1gua por um reagente \u00e1cido. O vapor de \u00e1gua \u00e9 removido ap\u00f3s ser arrefecido por um condensador e o di\u00f3xido de carbono \u00e9 removido utilizando um material n\u00e3o poroso.
\nO teor de carbono inorg\u00e2nico total (CIT) da amostra foi determinado por um detetor de infravermelhos n\u00e3o dispersivo (NDIR); carbono org\u00e2nico total (COT) = CT - CIT.<\/p>\n
