放射性纸层析扫描仪是由国营二六二厂研制的一种色谱测量仪器。该仪器由探头部分(为钟罩形半圆柱体气流式正比计数管)、扫描仪和定标器组成,工作气体采用90％氩气和10％甲烷的混合气。适用于测量放射低能β(~3H、~(14)C等)、γ(~(125)I等)的放射性核素,能定性定量分析放射性标记化合物各组份的含量,广泛用于放射化学、核医学和放射生物学等领域的研究工作。我们对该仪器的性能(包括本底、效率、灵敏度以及位置分辨能力等)进行了测试和评价,并与其它测量方法做了对比。
Radiological paper chromatography scanner is developed by State-owned 260 plants a chromatographic measurement instrument. The instrument consists of a probe section (bell-shaped half-cylinder air flow proportional counter), a scanner and a scaler. The working gas is a mixture of 90% argon and 10% methane. It is suitable for the determination of radionuclides that emit low-energy β (~ 3H, ~ (14) C etc.), γ (~ (125) I, etc.) and can qualitatively and quantitatively analyze the content of each component of radiolabeled compounds. , Nuclear medicine and radiobiology and other fields of research work. We tested and evaluated the instrument’s performance (including background, efficiency, sensitivity, position resolution, etc.) and compared it with other measurements.
