Abstract Diffusive Gradients in Thin-films (DGT) is an in situ passive sampler with a
widespread use in environmental studies. Within the ample range of analytes that can be …

Highlights What are the main findings? AGNES technique determines free metal ion
concentrations; AGNES principles lead to a very robust determination when suitable checks …

Several electroanalytical techniques (such as Absence of Gradients and Nernstian
Equilibrium Stripping, AGNES) need to quantify the amount of reduced analyte (M 0) pre …

The speciation of essential metal ions in biological fluids, such as blood plasma and serum,
is of fundamental importance to understand the homeostasis of these elements. The activity …

Abstract Indium oxide (In 2 O 3) nanoparticles (NPs) are used in electronic devices, from
which indium (as its nanoparticulate form or as other generated chemical species) can be …

Diffusion cells are used to measure diffusion coefficients (DM) in gels. These measurements
are of interest to understand and predict the availability of nutritive or toxic chemical species …

Determining species, concentrations, and physicochemical parameters in natural waters is
key to improve our understanding of the functioning of these ecosystems. Diffusive Gradients …

An historical overview covering the field of electroanalytical metal cations speciation in
freshwaters is presented here, detailing both the notable experimental and theoretical …
