Abstract
An arrangement for counting liquid scintillation samples on a sample plate in a liquid scintillation counter having at least one photomultiplier tube. The sample plate contains a plurality of open-bottomed wells sealed with at least one filtration membrane impregnated with a solid meltable scintillator. The arrangement includes a sample plate holder for holding and transporting the sample plate in the liquid scintillation counter. The holder includes a device to hold sample plates of different sizes and a device to enable transportation of the sample plate in the liquid scintillation counter.
Claims5
An arrangement for counting of liquid scintillation samples comprising in combination
- (a) a liquid scintillation counter comprising at least one photomultiplier tube,
