Abstract
An arrangement for improving the counting of liquid scintillation samples including a plurality of separate sample wells, a plate holder surrounding the sides of each sample well so that each plate holder forms an optically separate compartment for each sample well, at least one photomultiplier tube adjacent each sample well, and a coating of light reflective or light scattering material on the inner surfaces of said plate holders.

An arrangement for improving the counting of liquid scintillation samples comprising in combination
- (a) a plurality of separate sample wells (11),
- (b) a holder (12) surrounding the sides of each sample well (11) so that each holder (12) forms an optically separate compartment for each sample well (11),
- (c) photomultiplier tubes (14) positioned above and below each sample well (11), and
- (d) a coating of light reflective or light scattering material (17) on the inner surfaces of the holders (12).
