Abstract
A process and apparatus for the voltammetric measurement of sample component quantities is disclosed wherein the material to be measured is passed by means of a pulsating-delivery pump into a voltammetric cell by way of a flow cross-section restriction to the surface of the voltammetric electrode, the liquid jet being adjusted such that its cross-section in the vicinity of the measuring surface of the electrode should be greater than the measurement area of the latter. The obtained voltammetric current curve is integrated at the area below the peak value, the current changing as a function of the pulsating flow rate of the liquid and the material quantities are determined from the integrated data. Preferably, the integration is effected from a value corresponding to 50% of the maximum flow rate to the maximum value and from there again down to 50% of the flow rate maximum.
