The device contains a rotatable block (carousel) with three ports for working electrodes, which can be easily chosen (changed) by a rotation of the carousel. The method takes advantage of the high reactivity of electrochemically generated metallic ions "in statu nascendi". The device is suitable for ionization of various organic compounds (e.g., lipids, lipoproteins, pesticides, drugs, metabolites, lipids, lipoproteins) in biological and other matrices. The wide range of applications is made possible by the selection from three different solid electrodes placed in the carousel. This technical upgrade allows providing a number of possible chemical adducts and hereby the method can be tailored according to specific demands. The applicability of the electrochemical device is demonstrated by the electrochemical activation of pesticide cyproconazole (Cyp) in a soil solution matrix via formation of its adducts with Ag and Cu cations, generated from the working electrode material. The metal/Cyp adducts are on-line detected using an electrospray ionization mass spectrometer.
