“…1). In the phenethylamine-Aquasol cocktail it was stable at 25 h and has been reported stable up to 72 h in a phenethylamine-toluene-methanol cocktail (Davis et al 1975).…”
Carbon‐14 activity was lost when 14C‐NaHCO3 in aqueous solution was added to Aquasol. Phenethylamine can be used to form carbamates which are stable in Aquasol in order to achieve complete retention of 14C in the liquid scintillation cocktail.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
