<P>PROBLEM TO BE SOLVED: To provide a filtration membrane evaluation system which can determine the molecular weight fractionation of a filtration membrane in a short time even when using a plurality of molecular weight standard substances of different average molecular weights for three or more kinds or the like. <P>SOLUTION: The filtration membrane evaluation system includes: a cross flow filtration device 1 which filters circulation liquid composed by dissolving the plurality of molecular weight standard substances; a liquid chromatography 2 which samples filtrate and the circulation liquid respectively from the cross flow filtration device 1 and obtains the chromatogram of the filtrate and the circulation liquid; and an analysis device 3 which can determine the molecular weight fractionation of the filtration membrane by analyzing the peak area of the plurality of molecular weight standard substances from the chromatogram of the filtrate and the circulation liquid, calculating the blocking rate of the molecular weight standard substances from the peak area of the filtrate and the peak area of the circulation liquid, and plotting the calculated blocking rate of the plurality of molecular weight standard substances. <P>COPYRIGHT: (C)2012,JPO&INPIT |
