Description
| - To reach higher sensitivity in metal analysis we developed convenient sample pre-concentra- tion method which was on-line combined with common analytical ITP. Developed pre-concentration method is based on the principle of stationary neutralization reaction boundary-NRB and its combination with ligand - chelating agents. A stationary ligand step gradient -- LSG [1] boundary is created in the column with two adjacent electrolytes branches of different chelating power and pH. In acid phase, metal and metal complexes are positively charged and forced migrate to the LSG boundary, in the alkaline phase, the complexes are negatively charged and again migrate towards LSG-boundary. A steady state zone of concentrated metal complexes is created. Focused zones are then mobilized and analyzed by ITP. Presence of sample metal ions in one electrolyte /dosing elektrolyte-DE/ during the focusing causes a time dependent accumulation of the metals
