Title
(EN) METHOD AND APPARATUS FOR OBTAINING ANALYTES FROM LIQUID MENSTRUA FOR ANALYSIS
(FR) METHODE ET APPAREIL POUR OBTENIR DES ANALYTES A PARTIR D'ECHANTILLONS LIQUIDES POUR ANALYSES
Abstract
(EN)
Solutes are obtained from liquid menstrua by bubbling gas through the liquid menstrua wherein solute passes to the interface between the bubble and the liquid menstruum and/or into the gas within the bubble. The bubble breaks the surface of the liquid menstruum and defines an entrainment zone which is subjected to electromagnetic radiation to maintain solute in the vapor space. The recovered solute may, for instance, be subjected to analytical analysis.
(FR)
On obtient des solutés à partir d'échantillons liquides en insufflant des bulles de gaz dans les échantillons liquides, ce qui amène le soluté à passer à la surface de liaison entre la bulle et l'échantillon liquide et/ou dans le gaz contenu dans la bulle. Celle-ci brise la surface de l'échantillon liquide et délimite une zone d'entraînement soumise à un rayonnement électromagnétique pour maintenir le soluté dans le compartiment à vapeur. Le soluté récupéré peut alors, par exemple, être soumis à analyse.
