⚠️ 5 Common Beginner Mistakes
- ① Unpolished electrode harming reproducibility
- ② Residual oxygen causing interfering peaks
- ③ Inappropriate supporting electrolyte
- ④ Poor scan parameters giving bad peak shape
- ⑤ Drifting reference electrode
❓ FAQ
+Why supporting electrolyte?
Enhances conductivity, stabilizes potential and peak shape.
+Is stripping more sensitive than DPV?
Yes, pre-concentration greatly boosts sensitivity.
+Electrode maintenance?
Polish regularly and clean/store after use.
