Abstract
A new type of asymmetric flow field flow fractionator, A4F, is described permitting improved sample fractionation means by providing a range of available channel lengths within the same A4F unit. With such an apparatus, samples may be optimally separated by performing such fractionations as a function of channel length. The ability to vary channel length within the same A4F unit has heretofore been unavailable.
