Simultaneous determination of captopril and hydrochlorothiazide on boron-doped diamond electrode by batch injection analysis with multiple pulse amperometric detection

- Fast simultaneous determination of captopril and hydrochlorothiazide.
- Minimal sample manipulation (dissolution and dilution in electrolyte).
- Simultaneous determination with a single injection step (100 injections h−1).
- Rapid detection of the presence of electroactive interferents (fast screening test).
