流动注射分析法已渗透于分析化学的各个领域。作为水样品预富集和引入检测器的有力手段之一,配有微型柱的流动注射在线富集进样系统,己越来越广泛地用于原子光谱检测器上。本文第一部分对富集无机元素的不同柱填充材料的性能和应用作了非常简要的分类和介 Flow injection analysis has penetrated all areas of analytical chemistry. As a powerful tool for pre-enrichment of water samples and introduction of detectors, flow injection on-line enrichment injections systems equipped with miniature columns have become more and more popular for use with atomic spectroscopy detectors. The first part of this article makes a very brief classification and introduction of the properties and applications of different column packing materials enriched in inorganic elements
