Determination of micelle size in some commercial liquid scintillation cocktails

Abstract

We performed dynamic light scattering measurements on commercially available liquid scintillation (LS) cocktails over a range of aqueous and acid contents. In all cases, we measured hydrodynamic diameters substantially smaller than the current de facto canonical value of 8 nm. We describe the cocktail compositions that yield stable micelles and report the observed diameters. We also discuss calculations of the magnitude of the "micelle effect" on LS counting efficiencies and the error introduced by adopting an incorrect value for the micelle size.
