Abstract: Column packings play the key role in chromatography, one of the most important technologies in bioseparation. An information system is constructed, with a database containing data on media physical and performance properties, stability, manufactures and related references. Information of nearly 200 media ranging from ion exchange, hydrophobic interaction and gel filtration chromatography are collected. The comprehensive evaluation system is targeted to ion exchangers with selection and evaluation functions. It can both select out media with satisfactory stability and can evaluate ion exchanges systematically on their chromatographic properties. The information system is constructed by Microsoft Access 2000 with Visual Basic for Application (VBA). There are 26M bytes data at present.
