Abstract
An invention for preventing optical crosstalk in a process of counting liquid scintillation samples deposited in a sample plate, the sample plate composed of a plurality of sample wells, the optical crosstalk being caused by mutual optical affection between samples deposited in the sample wells. Sample wells are provided with tubes made of material impermeable but reflective or scattering for scintillation light generated by the samples.

A method for counting scintillation samples with a liquid scintillation counter comprising the steps of:
- providing a sample plate having a plurality of sample wells for containing said scintillation samples,
- positioning into each of said sample wells to be investigated a tube having an outer diameter equal to or slightly less than an inner diameter of said sample well, said tube made of material impermeable for scintillation light generated by said scintillation samples, said tube thereby preventing optical crosstalk between adjacent sample wells, and
- counting said samples with said liquid scintillation counter.
An apparatus for preventing optical crosstalk in a process of counting liquid scintillation samples deposited in a sample plate, the apparatus comprising:
- a sample plate having a plurality of sample wells, and
- a plurality of tubes mad of material impermeable for scintillation light generated by said samples, respective ones of said tubes positioned within respective ones of said plurality of sample wells.
