Prozessüberwachung eines chromatographischen Verfahrens der Kerntechnik

A chromatographic separation can be controlled only by the determination of the separated component concentration in the column effluent. This control is implemented by an in-line scintillation counting procedure during an extraction chromatographic purification of predecontaminated Th-containing fuel solutions from Np and Pu. In addition, the throughput ofthe process feed solution is determined, and the measuring signals of both determinations are used by appropriated control circuits to regulate the process operation and to perceive the process incidents.
