Chronamperometry
WebChronoamperometry (CA) or Amperiometric Detection is a simple, widely used electrochemical measurement technique. Many sensors, like those for glucose or oxygen, require this technique. Signal applied during … WebNov 17, 2024 · Chronoamperometry is very powerful method for the quantitative analysis of a nucleation process. This useful technique leads to obtain the initial information about nucleation and growth mechanism in a studied system. Additionally, the amount of charge for deposition (dissolution) can be determined.
