Triton X-100 scintillant for carbon-14 labelled materials.

Abstract Touluene/Triton X-100 liquid scintillant has been found to possess excellent characteristics for the counting of a wide variety of carbon-14 labelled compounds. The counting characteristics of the liquid scintillant for aqueous samples containing carbon-14 and tritium were examined in detail. The liquid scintillant has a number of very useful properties. Materials which are poorly soluble or insoluble in organic solvents may be incorporated in large quantities, maintained as stable homogeneous solutions for extended periods of time and counted at high efficiency. The liquid scintillant shows considerable resistance to quenching effects from aqueous samples, particularly aqueous acids.
