Abstract
A liquid scintillation cocktail especially suitable for low volume biological specimens comprising an aromatic liquid, preferably pseudocumene, for capturing energy from radiation, at least one fluor, preferably PPO and Bis-MSB, and a mixture of anionic and nonionic surfactants. The cocktails are prepared by treating with a cation exchange resin to clarify and with a solid buffer to raise the temperature at which cloudiness develops upon heating.
