Description Ten years ago the theory of elimination voltammetry with linear scan (EVLS) was published and experimentally verified for reversible, quasi-reversible and irreversible electrode systems1-3. The EVLS can be considered a mathematical model of the transformation of current-potential curves capable of eliminating some selected current components, and conserving the other ones. This contribution is devoted to the EVLS transformation of irreversible current-potential curves of an adsorbed electroactive substance. The function eliminating charging and kinetic current components, and conserving the diffusion current component, yields specific, sensitive and well developed peak-couterpeak (p-cp) signal3-5. Theoretical value of ratio Ip/(Ip+Icp) is 0,40973,5,8. This signal was successfully employed in the analysis of nucleic acids and short homo- or hetero-deoxyoligonucleotides (ODNs) containing adenine (A) and cytosine (C)4-12.
