Abstract
Procédé d'analyse de la teneur d'au moins un contaminant dans un liquide cryogénique dans lequel une quantité de liquide connue L constituant le liquide initial est introduite à la pression P dans une enceinte (E), une fraction déterminée du liquide présent dans l'enceinte est vaporisée en le chauffant, la vapeur ainsi générée (13) est évacuée de l'enceinte de vaporisation pour maintenir une pression égale ou inférieure à la pression P durant la phase de vaporisation, la quantité de liquide ainsi vaporisée, inférieure à L, est précisément contrôlée, de façon à ce que la quantité en contaminant dans le liquide résiduel présent dans l'enceinte soit substantiellement égale à celle dans le liquide initial, ce qui implique que sa concentration soit multipliée par un facteur préalablement déterminé, on prélève un échantillon de liquide résiduel, et mesure la teneur en contaminant après vaporisation totale de l'échantillon de liquide résiduel et on déduit de la mesure de contaminant dans le liquide résiduel la teneur en contaminant dans le liquide initial.
