Abstract: The combination of DPASV with ESI-MS allows a reliable detection of metal complexes with small organic ligands. The request to exact molecular mass is essential to stoichiometry design simultaneously with low concentration of the analyte in most of biological matrixes. By the analysis of model solution consisting of Cd(NO3)(2) and oxalic acid (OAH(2)) these structures were identified: [Cd(OAH(2))(H2O)(2)](+), [Cd(OAH(2))(H2O)(3)](+), and [Cd(OAH(2))(H2O)(2)(CH3OH)](+). They were also found in soil solution.
