The nonlinear and nonstationary nature of Navier-Stokes equations produces fluid flows that can be noticeably different in appearance with subtle changes. In this paper, we introduce a method that can analyze the intrinsic multiscale features of flow fields from a decomposition point of view, by using the Hilbert-Huang transform method on 3D fluid ...

Asymmetric Flow Field-Flow Fractionation in the Field of Nanomedicine
Analytical Chemistry, 2014Asymmetric flow field-flow fractionation (AF4) is a widely used and versatile technique in the family of field-flow fractionations, indicated by a rapidly increasing number of publications. It represents a gentle separation and characterization method, where nonspecific interactions are reduced to a minimum, allows a broad separation range from several

Field‐programmed flow field‐flow fractionation
Journal of Microcolumn Separations, 1995AbstractA flow field‐flow fractionation (FIFFF) system capable of accurate and reproducible flowrate programming has been assembled and tested. This modified system consists of three computer‐controllable pumps, two that regulate the incoming and outgoing cross flowrates and one that controls the channel flowrate.

Field and flow programming in frit-inlet asymmetrical flow field-flow fractionation
Journal of Chromatography A, 2002The separation of wide molecular mass (Mr) ranges of macromolecules using frit inlet asymmetrical flow field-flow fractionation (FI-AFlFFF) has been improved by implementing a combination of field and flow programming. In this first implementation, field strength (governed by the cross flow-rate through the membrane-covered accumulation wall) is ...

Dual-field and flow-programmed lift hyperlayer field-flow fractionation
Analytical Chemistry, 1992Field and flow programming and their combination, dual programming, are shown to extend the particle size range to which a single flow/hyperlayer field-flow fractionation (FFF) run is applicable to approximately 1-50 microns. The rationale for programming flow/hyperlayer FFF (or other forms of lift hyperlayer FFF) is to expand the diameter range of ...

On the no-field method for void time determination in flow field-flow fractionation
Journal of Chromatography A, 2011Elution time measurements of colloidal particles injected in a symmetrical flow field-flow fractionation (flow FFF) system when the inlet and outlet cross-flow connections are closed have been performed. This no-field method has been proposed earlier for void time (and void volume) determination in flow FFF Giddings et al. (1977).

Field-flow fractionation (FFF) is a family of instrumental techniques that separates and characterizes macromolecules, colloids, and particles (macromaterials) on an analytical scale (Colfen and Antonietti, 2000; Schimpf et al., 2000). As illustrated in Fig. 1, the FFF channel has a ribbon-shaped geometry, typically with length 30-50 cm, breadth 1-3 cm,
