Analysis of the Effect of Column Diameter on the Performance of Preparative Chromatography

GUO Wei,ZHOU Wei-hong(University of Science and Technology Liaoning,Liaoning Anshan 114044,China)  
Preparative chromatography was the better method to get high purity drug intermediates.The choice of the column diameter was the key problem in separation process with preparative chromatography.In the application of preparative chromatography,the pressure and column efficiency were two important parameters.So it was important to analyze the effect of column diameter on pressure and column efficiency.Based on the measurement of the column parameters,the effect of column diameter on pressure and column efficiency was studied.The result showed with the column diameter increased,the porosity of column reduced,column pressure was not increased with the column diameter increased,and the increase was a multiple of the square,and column efficiency increased with the increase of column diameter
