Recovery, overloading, and protein interactions in asymmetrical flow field-flow fractionation [PDF]

Analytical and Bioanalytical Chemistry, 2019
In asymmetrical flow field-flow fractionation (AF4), similar to other separation techniques, mass recovery and overloading require special attention in order to obtain quantitative results. We conducted a systematic study with five globular proteins of different molecular weight (36.7-669 kDa) and isoelectric point (4.0-6.5), and ultrafiltration ...

Beyond microplastics - investigation on health impacts of submicron and nanoplastic particles after oral uptake in vitro

Microplastics and Nanoplastics, 2022
The continuously increasing use of plastics is supposed to result in a rising exposure of MNPs to humans. Available data on human health risks of microplastics after oral uptake increased immensely in the past years and indicates very likely only low ...

Fractionation of Nanoparticle Matter in Red Wines Using Asymmetrical Flow Field-Flow Fractionation [PDF]

Journal of Agricultural and Food Chemistry, 2020
The particle matter of wine is mainly composed of wine colloids and macromolecules. The present work develops a methodology using asymmetrical flow field-flow fractionation coupled with multi-angle light scattering, differential refractive index detector, and ultraviolet detector (AsFlFFF-MALS-dRI-UV) for the fractionation and determination of the ...

Size-Resolved Fluorescence Underscores Negligible Interaction of Dissolved Organic Matter During Conservative Mixing in a Large Boreal River

Frontiers in Environmental Chemistry, 2022
Although river mixing occurs widely in nature, the corresponding evolution of dissolved organic matter (DOM) composition remains poorly understood. Here, surface water samples were collected at multiple transects in the lower Athabasca River (LAR) under ...
