Voltammetric analysis 2.3 Normal pulse voltammetry 2.3 Normal pulse voltammetry Fig. 2 Normal pulse voltammetry While applying sampled dc, the reactions are allowed to proceed during the whole interval time. As a result, the region near the electrode is depleted from reactant, lowering the faradaic current. Furthermore, reaction product can accumulate on the electrode, poisoning its surface. To decrease these detrimental effects, the normal pulse technique was developed. Here, the electrode is kept at an inactive potential for most of the interval time: the base potential. Just prior to the measurement, the electrolysis potential is applied: the normal pulse. Concerning the duration of the pulse period, the familiar discussion applies here: a shorter pulse will yield response with a higher magnitude but the ratio of (unwanted) capacitive current will be higher as well. This technique is approximately a factor 10 more sensitive than sampled dc. However, the data analysis is more complicated. Furthermore, since the time scale employed is shorter, it is possible to experience effects due to irreversibility of the electrode reaction. Then again, that might be just the objective. The parameters for this method are chosen similarly to sampled dc, with the addition of a pulse time. Normally, a reasonable value for the pulse time would be about 50ms. Internally, the software will try to adopt a sampling period that complies the line period. When the pulse period is larger than 40ms, it will collect samples and average them during the last 20ms (for 50Hz line frequency). |
