Abstract
Disclosed herein is a liquid scintillation solution useful for alpha particle emission and beta particle emission discrimination. Most preferably, the liquid scintillation solution comprises at least one naphthalene derivative enhancing agent; at least one solvent; and at least one fluor. In a particularly preferred embodiment, the liquid scintillation solution comprises di-isopropyl naphthalene as the enhancing agent; phenylxylethane as the solvent; and 2-(4'-biphenyl)-6-phenylbenzoxazote as the fluor.
Claims18
A method for discriminating between alpha emissions and beta emissions in a sample, said method comprising the steps:
- a) providing an alpha-beta discrimination sample solution comprising:
- i) at least one naphthalene derivative, said derivative comprising naphthalene and at least two alkyl groups where the alkyl groups are co-planar with said naphthalene;
- ii) at least one fluor;
- and
- iii) radioactive analyte comprising at least one beta emitter and at least one alpha emitter;
- (b) obtaining an emission spectrum of said beta emitter and said alpha emitter, wherein said emission spectrum provides information sufficient for quantitating said beta emitter and said alpha emitter.
