该工作研制了一台ＦＩＡ－铀、镎、钚测定仪。该仪器综合了流动注射与色谱分析的优点；为适应放射性样品分析，仪器分为工作箱和控制箱两部分，两箱间距离为１．５ｍ；仪器抗干扰能力强，样品中允许大量杂质存在；信号的基线平稳，峰形尖锐；定量测定下限为１ｍｇ／ｌ，相对标准偏差优于５％；适用于１ＡＦ，１ＡＰ等许多控制点对Ｕ、Ｎｐ、Ｐｕ的分析。 The work developed a FIA-uranium, uranium, plutonium detector. The instrument combines the advantages of flow injection and chromatographic analysis; in order to meet the radioactive sample analysis, the instrument is divided into two parts of the work box and the control box, the distance between the two boxes is 1.5m; instrument anti-interference ability, allowing a large number of impurities in the sample ; The baseline of the signal is stable and the peak shape is sharp; the lower limit of quantitation is 1mg / l, the relative standard deviation is better than 5%; it is suitable for the analysis of U, Np, Pu in many control points such as 1AF and 1AP.
