A new design for a liquid scintillation counter based on a flat-bed geometry is described. Micro-samples are dried or filtered onto transfer membranes or glass fibre filters in a 6 X 16 matrix, compatible with 96-well micro-titration plate filtration assays of labelled cells. A prototype counter without lead shielding had low background countrates (2-3 cpm for 3H) giving a figure of merit of 1325 (and 1292 for 14C). Only 5-15 ml of scintillant/96 samples are required and thus the volume of radioactive waste is low.
本文描述了一种基于平板几何结构的新型液体闪烁计数器设计。微量样品经干燥或过滤后，转移至6×16矩阵的转移膜或玻璃纤维滤膜上，该设计与标记细胞的96孔微量滴定板过滤分析兼容。一款无铅屏蔽的计数器原型具有较低的本底计数率（³H为2 - 3计数/分钟），品质因数为1325（¹⁴C为1292）。每96个样品仅需5 - 15毫升闪烁剂，因此放射性废物量较少。
