AB  - Electrochemical detection systems are very promising for pollution monitoring 
      owing to their easy miniaturization and low cost. For this purpose, we have 
      recently developed a new concept of device based on Electrodes Array for 
      Sampled-Current Voltammetry (EASCV), which is compatible with miniaturization and 
      portability. In this work, to improve the sensitivity of the analytical method, 
      we added a preconcentration step before EASCV analysis, combining sampled-current 
      voltammetry with anodic stripping voltammetry. Lead was chosen as analyte for 
      this probe of concept owing to its high toxicity. The conditions for 
      electrodeposition of lead on gold were optimized by means of under potential 
      deposition. Current intensities 300 times higher than with linear sweep anodic 
      stripping voltammetry were obtained, showing the interest in the method. The 
      value of the sampling time directly affected the sensitivity of the sensor given 
      by the slope of the linear calibration curve. The sensor exhibited a limit of 
      detection of 1.16 mg L(-1), similar to those obtained with linear sweep anodic 
      stripping voltammetry.
