Abstract
During the optimization of 36Cl determination in solid wastes from nuclear decommissioning, a residual 36Cl signal was
observed in procedural blanks measured after processing active samples. To uncover the possible causes, we investigated
the interaction of chlorine with the components of a Pyrolyser-6 Trio™, as well as the chemicals used during the procedure.
Different treatments for identifying the source of chlorine carryover were thoroughly investigated, demonstrating that the 36Cl
memory effect arises from the interaction with pyrolyser components and that it occurs almost every time when the analysis
procedure is performed. Therefore, results obtained using this analysis procedure need to be corrected for this memory effect
by measuring procedural blank samples before and after measuring 36Cl-containing samples.
