Title (EN) METHODS FOR ANALYZING ULTRA-TRACE AMOUNT OF METAL IN LIQUIDS
(FR) PROCÉDÉS D'ANALYSE DE TRACE INFIME DE MÉTAL DANS DES LIQUIDES
Abstract:
(EN) The present invention relates to a method of detecting one or more metals in a liquid sample. The method includes the step of extracting the metal from the liquid sample and retaining the metal on a binding material. The detection of the extracted metal can be performed with the metal retained on the binding material or after the elution of the metal off the binding material.
(FR) La présente invention concerne un procédé de détection d'un ou plusieurs métaux dans un échantillon de liquide. Le procédé comprend l'étape consistant à extraire le métal de l'échantillon de liquide et à retenir le métal sur un matériau de liaison. La détection du métal extrait peut être effectuée avec le métal retenu sur le matériau de liaison ou après l'élution du métal du matériau de liaison.
