Listening In on the Past: What Can Otolith δ18O Values Really Tell Us about the Environmental History of Fishes? [PDF]

, 2014
Oxygen isotope ratios from fish otoliths are used to discriminate marine stocks and reconstruct past climate, assuming that variations in otolith δ18O values closely reflect differences in temperature history of fish when accounting for salinity induced ...

Revision of the calibration experiment in asymmetrical flow field-flow fractionation

Journal of Chromatography A, 2021
Asymmetrical flow field-flow fractionation is a versatile chromatographic fractionation method. In combination with at least one detection technique it is used for size-based separation of colloids, biomolecules and polymers. Although often used as pure separation method, a well-elaborated theory is available that allows precise quantification of the ...
