Characterization of Silver Nanoparticles under Environmentally Relevant Conditions Using Asymmetrical Flow Field-Flow Fractionation (AF4). [PDF]
The development of methods to monitor manufactured nanomaterials in the environment is one of the crucial areas for the assessment of their risk. More specifically, particle size analysis is a key element, because many properties of nanomaterial are size

Increasing the resolution of field flow fractionation with increasing crossflow gradients
The resolution of flow field flow fractionation (flow FFF) depends primarily on the crossflow rate and its change over time. In this work we demonstrate a method for modulation of the crossflow rate during separation increases the peak-to-peak resolution

Nanoparticle separation with a miniaturized asymmetrical flow field-flow fractionation cartridge
Asymmetrical Flow Field-Flow Fractionation (AF4) is a separation technique applicable to particles over a wide size range. Despite the many advantages of AF4, its adoption in routine particle analysis is somewhat limited by the large footprint of ...

Experimental setup for the ultrasonic fractionation of flowing whole blood in a capillary
If a long ultrasound driving pulse is chosen such, that its frequency is greater than the resonance frequency of one cell type and less than the resonance frequency of another cell type, the cells are separated in different nodes and antinodes of the ...

Field-Flow Fractionation Analysis of Complex Biological Samples [PDF]
Normal analytical methods have difficulties when analysing complex samples containing particles of different size. In the 1960s, a new analytical technique was developed, which was able to overcome those difficulties.

Water-dispersible colloids distribution along an alluvial fan transect in hyper-arid Atacama Desert
As located in one of the oldest and driest deserts on Earth, soils in the Atacama Desert are greatly affected by atmospheric dust deposited on soil surface and the related fate of water-dispersible colloids (WDCs,
