Compact Disk-Interactive

The CD-I (compact disk-interactive) is a low cost alternative to the CD-ROM for the entertainment industry. CD-I is a subset of the CD-ROM standard data format. It allows the digital storage of data, audio, and video information in a form that permits rapid interaction with a computer. CD-I is compatible to CD-ROM and to CD-AD 0 = 120 mm. The definition of the CD-I format is put down in the Green Book (Philips/Sony).

In chromatographic separations using flat sheet membranes, compact porous disks, fibers, tubes, or rods, the interaction between the ligate molecule and the immobilized ligand takes place in the through-pores of the matrix and not in the dead-end pores of the conventional packed-bed particles. This method resembles affinity membrane separation with a very short affinity chromatography column [2].
