Optimisation of asymmetrical flow field flow fractionation for environmental nanoparticles separation

Journal of Chromatography A, 2008
The fractionation of natural nanoparticles by Asymmetrical Flow Field Flow Fractionation (As-Fl-FFF) was optimised by considering the following operating conditions: ionic strength, surfactant concentration and crossflow rate. The method performances such as fractionation recovery and fractionation efficiency were evaluated on a stable solution of ...

Field and flow programming in frit-inlet asymmetrical flow field-flow fractionation

Journal of Chromatography A, 2002
The 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 ...

Asymmetric Flow Field-Flow Fractionation in the Field of Nanomedicine

Analytical Chemistry, 2014
Asymmetric 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

Analysis of Peptides using Asymmetrical Flow Field-flow Fractionation (AF4)

Journal of Pharmaceutical Sciences, 2021
While asymmetrical flow field-flow fractionation (AF4) has been widely used for separation of high molecular weight species and even particles, its ability to resolve lower molecular weight species has rarely been explored. Over the course of many projects, we have discovered that AF4 can be an effective analytical method for separating peptides from ...

Analysis of plant ribosomes with asymmetric flow field-flow fractionation

Analytical and Bioanalytical Chemistry, 2013
Ribosome profiling is a technique used to separate ribosomal subunits, 80S ribosomes (monosomes), and polyribosomes (polysomes) from other RNA-protein complexes. It is traditionally performed in sucrose gradients. In this study, we used asymmetric flow field-flow fractionation (AsFlFFF) to characterize ribosome profiles of Nicotiana benthamiana plants.

Fractionation of Humic Substances by Asymmetrical Flow Field-Flow Fractionation

Chromatographia, 2005
Asymmetrical flow field-flow fractionation was used to investigate the effects of pH and ionic strength of the buffer, and the binding of polyaromatic hydrocarbons (PAHs) on the particle sizes of humic substances (HSs). Particle sizes were greater when HSs were present in acidic medium with phosphate buffer than when they were present in alkaline ...

Miniaturization of Frit Inlet Asymmetrical Flow Field-Flow Fractionation

Analytical Chemistry, 2004
A miniaturized frit inlet asymmetrical flow field-flow fractionation (mFI-AFlFFF) channel has been constructed and tested for the separation of proteins. By scaling down the geometrical channel dimension of a conventional FI-AFlFFF system, flow rate ranges that can be manipulated were decreased to 20-30 microL/min, which reduces the injection amount of
