The fluidization technique provides a solution to the problem of filling wide diameter columns used in preparative gas chromatography. The density of a packing after fluidization is uniform both in the direction of the column and across the diameter. When applied to preparative gas chromatographic columns, this feature of fluidization offers the possibility of obtaining a gas profile with the minimum of concavity. The average efficiency of a 6 cm I.D. column filled in this way is 315 plates per metre when 1.2 ml of a mixture of equal parts by weight of pentane and hexane is injected. The preparation of the columns is quick and reproducible with a performance independent of the operator. Since with a fluidized bed, heat transfer is at a maximum, the setting up of a column can be made more rapid by using carrier gas heated to the desired temerature for fluidizing the packing. © 1963.
