An on-line Ag/Al galvanic cell is investigated and employed to generate electrochemiluminescence (ECL). The potential of the galvanic cell could be adjusted by varying the components of flow reagent. The cell performed perfect capability of supplying a stable potential for ECL generation. Based on the weak ECL of calcein blue could be greatly sensitized by the presence of calcium in alkaline solution, calcium contents in milk samples and in cabbage were assayed and the results were compared with those from ICP-AES method.
