柱偶联装置在毛细管等速电泳中的应用
Application of Column-coupling in Capillary Isotachophoresis
【摘要】 根据自制的OCEP-1型离子分析仪的特点,设计了一套新的柱偶联装置。提高了分离容量,可以用来检测复杂混合物中的低浓度组分。用等速电泳法测定了高浓度Cl~-或Ac存在时的F~-。这个装置对于处理离子性组分,无论在研究工作还是实际分析工作中,都是很有用的。
【Abstract】 A new column-coupling device with improved separation capacity was introduced. It can be used to detect species at low concentration in complex mixtures. A high presepara-tion current is permitted, which results in a short separation time. The fluoride ion at low concentration level was determined when a high concentration ratio of chloride or acetate ion existed. This device should be highly useful in treating ionic species in research work as well as in practical analysis.
