The Distribution of Neutral Solute in Electrochromatography Column at Ultra-long Injecting Time

Zhang Weibing, Ping Guichen, Zhang Lingyi, Zhang Qinghe, Zhang Lihua, Zhang Yukui  (National Chromatographic Research & Analysis Center, Dalian Institute of Chemical Physics, Chinese Academy of Science, Dalian 116011)  
The effect of solute absorbed on the solid phase on its distribution in electro-chromatographic column was investigated according to relaxation theory. The distribution equation was theoretically gotten by production function. The result shows that neutral solute can be stayed in a narrow band near column head at ultra-long injecting time, indeed longer than dead-time. This process is similar to a solid-extraction. As an example,benzoin can be enriched 20000 fold with this method.
