✦ Synopsis
The counting rate of [ 1-r4C] trichloroacetic acid (TCA) was not stable in a standard toluene/Triton X-100 liquid scintillation solution because this compound becomes partially degraded to 14C0, and CHCl,. Both toluene and Triton were contributing factors in causing this degradation. The NCS solubilizer added to the toluene/Triton scintillation solution trapped %O, and stabilized counting rates of [I-14C]TCA. When [2-14C]TCA was used, '"CHCI, remained in the scintillation solution resulting in stable counting rates without the addition of NCS.
