摘要：

A new approach to current sampling in amperometric and polarographic measurement is described. This approach requires the application of a step-by-step mode of mercury drop generation. The advantages are: (1) in amperometric measurements an increase of the signal to noise ratio; (2) in polarographic measurements and computer aided experiments the noise level can be markedly reduced.
