一、概述在生物化学、分子生物学、药物学等研究工作中,经常要对被研究的样品的成分进行分离、纯化和鉴定.分离、纯化的方法,通常是采用柱层析法.本检测仪是用于检测柱层析下柱洗脱液样品中核酸和蛋白质浓度变化的仪器.它可以直接记录柱层析洗脱曲线,因而实验者不必花费大量时间对下柱洗脱液逐管在紫外分光光度计上进行检测(洗脱液有时可达700～ I. Overview In biochemistry, molecular biology, pharmacology and other research work, often to be studied in the sample components were isolated, purified and identified.Isolation and purification methods, usually by column chromatography method of this test The instrument is used to detect changes in the concentration of nucleic acids and proteins in a column eluate sample, which records the column elution curve directly, so the experimenter does not have to spend a significant amount of time on the column eluant tube by tube at UV spectrophotometer for detection (eluent sometimes up to 700 ~
