本实验以胺基膦酸树脂富集试样中的痕量成分,研制用于在线富集AAS测定的高效富集器,利用这种高效富集器可将原有分析方法灵敏度提高20-140倍。
In this experiment, amino-phosphonic acid resin was used to enrich trace elements in the sample to develop an efficient enrichment device for on-line enrichment AAS determination. By using this highly efficient enrichment device, the sensitivity of the original analysis method can be improved by 20-140 Times
