    • Comparison of different speciation techniques to measure Zn availability in hydroponic media 

      Companys Ferran, Encarnació; Galceran i Nogués, Josep; Puy Llorens, Jaume; Sedó, Maria; Vera, Ruben; Anticó, Enriqueta; Fontàs, Claudia (Elsevier, 2018-12)
      Four analytical techniques are compared: AGNES (Absence of Gradients and Nernstian Equilibrium Stripping), LASV (Anodic Stripping Voltammetry with Linear stripping), DGT (Diffusive Gradients in Thin films) and PIM (Polymer ...
    • Free Zn2+ determination in systems with Zn-Glutathione 

      Lao, Mireia; Dago Busquets, Àngela; Serrano, N.; Companys Ferran, Encarnació; Puy Llorens, Jaume; Galceran i Nogués, Josep (Elsevier, 2015-11-01)
      Zn-Glutathione speciation was studied applying the electrochemical technique AGNES (Absence of Gradients and Nernstian Equilibrium Stripping) to determine the free zinc concentration. In titrations varying either pH, total ...
    • Speciation of Zn, Fe, Ca and Mg in wine with the Donnan Membrane Technique 

      Lao, Mireia; Companys Ferran, Encarnació; Weng, Liping; Puy Llorens, Jaume; Galceran i Nogués, Josep (Elsevier, 2018)
      Free concentrations of Zn2+, Fe3+, Ca2+ and Mg2+ in a red wine (Raimat, Catalonia, Spain) have been determined, with the Donnan Membrane Technique (DMT) for the first time. The required equilibration time benefits from the ...
