I know Differential Pulse Voltametry is using to measure LOD value. But I do not know how to measure the Lowest Detection Limit of a sensor in Electrochemical sensing. Please reply. Thanks.
Hello Akhin Vp
The limit of detection (LOD) corresponds to the lowest concentration of analyze that could be detected from your electrochemical sensor system with a signal sufficiently separated from the background noise. Generally it is at least a signal three times bigger than the noise or outside of the error range of your control.
I would also suggest to look at this article Article Limit of Blank, Limit of Detection and Limit of Quantitation
mentionnes in this RG discussion https://www.researchgate.net/post/How_to_calculate_Sensitivity_and_LOD_from_Amperometry_resultsBest regards,

There are many methods you can use.
