CONT

Pour appliquer à des quantités infimes de matière des méthodes de séparation dont les performances ont été déterminées sur des quantités pondérables d’éléments, Seaborg utilisa systématiquement ce que l'on nomme l'ultramicrochimie. C'est-à-dire l'exécution d’opérations chimiques sur des quantités très faibles mais à des concentrations analogues à celles utilisées pour les études des méthodes de séparation.
