The Diffusive Gradients in Thin Films (DGT) technique is an in situ and preconcentration method which has been widely developed to measure either inorganic or organic contaminants using different resin layers in aquatic environment. However, it was never considered to use a single resin, containing multiple functional groups, for simultaneous determination of inorganic and organic compounds by a universal passive sampler. A new DGT sampler using an environmentally friendly Capterall Mersorb (CM) binding layer for simultaneous measurements of ten trace metals (Cd, Zn, Cr, Mn, Co, Ni, Cu, Pb, ...
