OSTI ID:4810449
A new approach to instrumentation for dropping mercury polarography is developed. The dropping mercury electrode (DME) current is converted to a voltage by a d-c negative feedback amplifier. The output of this amplifier is sampled at a fixed delay after the drop fall. The value of each sample is stored on a capacitor and succcssive differences are taken by a simple switching arrangement. The instrument includes a precise potential supply for the polarographic cell which may be used for scanning or location of the half wave potential. Drop fall is detected by the change in an r-f signal, and accurate timing circuits control the sampling and display. (auth)
