摘要
对比分析了国内外几种典型制样系统的优劣,重点介绍了作者改进的常规^(14)C制样系统。改进后的制样系统将燃烧单元、酸解单元、气体纯化单元、合成碳化物单元、合成苯单元、温度、电路控制单元有机地连接在一起,可在系统上同时分段、并行、灵活、方便的操作多个样品,相互之间不受时间的约束和影响,提高了工作效率。
In this paper, a comparison of several typical sample preparation systems for ^14C determination is made and an improved conventional sample preparation system proposed by the author is introduced. In the new system, burning unit, digestion unit, gas-purification unit, carbide-synthesis unit, benzene-synthesis unit, as well as temperature and electrocircuit-control unit are well integrated. And simultaneous multi-sample treatment function with advantages of flexibility, conveniency and high efficiency is provided by the new system.
