- •
PDA/PMOX-EI coating was formed via one-step on inner surface of the capillary.
- •
Melamine in milk powder was determined by PDA/PMOXA-EI coated capillary using CE.
- •
Solvent extraction for the pretreatment of sample is not needed in this method.
- •
CE running procedure is simple and convenient without additional NaOH rinsing step.
- •
Our coating could be still used to detect melamine after being used for 45 days.
