摘要：
A new technique for the separation and characterization of particles and polymers based on asymmetrical flow field-flow fractionation was developed. The new circular asymmetrical flow field-flow fractionation instrument (CAFFFE) resembles a quasi-parallel arrangement of 12 individual flow channels. As compared to the classical asymmetrical flow field-flow fractionation (AF-FFF), which can be used so far only for analytical separation and characterization of particles and polymers, the CAFFFE allows the introduction of higher amounts of sample into the channel in a single run so that semipreparative to preparative separation becomes possible. This was demonstrated by the separation of polymer latex standards.
