Abstract

resumo “método para testar um sistema, sistema para detectar pelo menos um gás analito e método para testar pelo menos um caminho de transporte em um sistema” um método para testar um sistema (10), o qual tem pelo menos um sensor eletroquímico (40) para detectar um gás analito no interior de um alojamento (20) do sistema (10), e um alojamento (20) tem uma entrada (22), inclui exalar nas proximidades da entrada (22) do alojamento (20) do sistema (10) e medir uma resposta ao ar exalado para testar um ou mais caminhos de transporte do sistema. a medição da resposta ao ar exalado pode, por exemplo, incluir a medição da resposta de um sensor (40) dentro do alojamento (20) do sistema que é responsivo à presença de ar exalado. o sensor responsivo à presença de ar exalado pode, por exemplo, incluir um eletrodo eletroquimicamente ativo responsivo a um gás dentro do ar exalado. o eletrodo eletroquimicamente ativo pode, por exemplo, ser responsivo ao dióxido de carbono ou ao oxigênio. 1/1
