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 … WebSometimes called chronoamperometry, or constant potential recording. A fixed potential is held at the working electrode and the current flow monitored with time. Chart software is typically used to record results. With Chart you can also use the Computed Function Integral to integrate the signal over to perform coulometric recording.
