《Analytica Chimica Acta》1992年264卷刊登了J.L.P.Pav on等人关于在线预富集-流动注射测定钍、铀的文章。该文叙述了流动注射的流路设计、树脂选择、取样体积、样品pH及盐分、方法精密度、实际样品考核等实验情况。流路中有两个六通注射阀。第一个阀装有预富集微型柱,第二个阀装有还原微型柱。两个微型柱均为5cm×2mm(内径)的玻璃管。富集柱中装
Analytica Chimica Acta, 1992, Volume 264, published an article by J.L.P. Pavon et al. On online preconcentration - flow injection determination of thorium and uranium. This article describes the flow injection injection flow path design, resin selection, sampling volume, sample pH and salt, the method precision, the actual sample test and other experimental conditions. There are two six-way injection valve in the flow path. The first valve is equipped with a pre-enriched miniature column and the second with a reduced miniature column. Both mini columns are 5 cm x 2 mm (inner diameter) glass tubes. Enrichment column loaded
