We started to produce our in house screen printed electrode. I want to check reproducibility in a single batch and batch to batch variation.
I did CV and considered the first cycle and measured current in a specific potential and i did the statistical calculation for RSD below 5. I totally did it on my own ideas. I was wondering if there is a kind of approved model protocol for that?
That's correct. For reproducibility (measuring variation between different electrodes made by the same methods), you should measure the same fresh sample with different electrodes and calculate the RSD for 5-10 peak current measurements. For reusability (repeatability), use one electrode and repeat measuring the same sample 5-10 times, then calculate the RSD for different cycles of the same samples.
