METHOD FOR VOLTAMETRIC MEASUREMENT OF VERY LOW VOLTAGE USING FEW COMPONENTS |
摘要 |
The invention relates to a simplified and improved method to carry out very sensitive voltametric measurements. The pre-determined voltage between the electrolyte and the collector is not obtained by readjusting the electrolyte potential, but by an autonomous regulating circuit which maintains the potential grounded. This provides the advantage that the slightest difference in potential is detected in the operational amplifiers and that the regulator adjusts an equivalent current by means of the load resistor. Said circuit has a limited use in fast cyclovoltametric applications since the regulating distance of the integrator used is longer in comparison with direct compensation. |
