Environmental solid matrices - Determination of total dissolved solids (TDS) in water and eluates

Le présent document spécifie une méthode permettant de déterminer la concentration en matières solides dissoutes totales (TDS) dans l'eau et les éluats pourvu que ces matières ne soient pas volatiles dans les conditions spécifiées ou qu'elles ne relarguent pas de molécules d'eau d'hydratation. Il s'applique à l'eau et aux éluats contenant plus de 100 mg/l de matières solides dissoutes totales. Les échantillons contenant des quantités moindres de matières solides dissoutes peuvent être analysés en répétant l'étape de dessiccation.
