Claims
- 1. A liquid scintillation counting composition, comprising a radioimmunoassay sample and a material having the following structural formula: ##STR2## in which y is from about 18 to about 50, and x and z are such that the total [CH.sub.2 --CH.sub.2 --O] content is from about 10% to 30% by weight of the molecule.
- 2. The composition of claim 1, in which the radioimmunoassay sample comprises inorganic salts and an animal blood fraction.
- 3. The composition of claim 1, further comprising at least one organic solvent.
- 4. The composition of claim 3, further comprising a scintillating solute.
- 5. The composition of claim 4, in which y is about 35.
- 6. The composition of claim 4, in which y is about 20.
- 7. A method of liquid scintillation counting comprising mixing a radioimmunoassay sample to be analyzed with a liquid scintillation composition comprising a mixture of a first material having the following structural formula: ##STR3## in which y is from about 15 to 56 and x and z are from about 1 to about 35, and a second material having the following structural formula: ##STR4## in which y' is from about 15 to about 56 and x' and z' are from about 1 to 35, and exposing the liquid scintillation composition to a scintillation counter.
- 8. A method of analyzing radioimmunoassay samples, comprising mixing the radioimmunoassay sample to be analyzed with a liquid scintillation composition comprising a material of the following structural formula: ##STR5## in which y is from about 18 to about 50 and x and z are such that the total [CH.sub.2 --CH.sub.2 --O] content is from about 10% to 30% by weight of the molecule.
- 9. The method of claim 7, in which y and y' are from about 18 to about 50, and the total [CH.sub.2 --CH.sub.2 --O] contents are from about 10% to about 30% of the total weight in both molecules.
- 10. The method of claim 9 in which y is from about 30 to 56 and y' is from about 15 to 30.
- 11. The method of claim 10 in which y is about 35 and y' is about 20.
