[Comparison of the separation performances between semi-preparative chromatographic column and chromatographic pie].
By comparing the resolution and recoveries of proteins between semi-preparative chromatographic column and chromatographic pie (pie-like column) having the same geometric volume under the same chromatographic conditions, the result from the former was found to have the almost same as that form the latter. However, the back pressure of the chromatographic pie rose slower than that of the chromatographic column with the increase of flow rate. Furthermore, the mass and volume loads for the chromatographic pie were higher than those for the chromatographic column. The results indicated that the chromatographic pie had more advantages than the chromatographic column in their performances, and this lay a foundation of the applications of the chromatographic pie in industry.
