Abstract
An improved channel for separation of molecular and particulate samples by means of electrical field flow fractionation (FFF) is disclosed. The electrodes therein are made of metal oxide coated flat glass plates and permit the achievement, thereby, all of the seven most desirable features for such an electrical FFF channel, viz. 1) hardness, 2) flatness, 3) smoothness, 4) chemical inertness, 5) durability (does not generate particles), 6) high conductivity, and 7) transparency. In addition, the design of the clamping plates permits high precision in aligning the electrodes for parallelism.
