Fast and simultaneous determination of nimesulide and paracetamol by batch injection analysis with amperometric detection on bare boron-doped diamond electrode

A fast and simple procedure for simultaneous determination of nimesulide and paracetamol (acetaminophen) was carried out by batch injection analysis with multiple pulse amperometric detection (BIA-MPA). The purpose is achieved with a unique and simple injection of a sample aliquot (150μL) onto the u...

Zusammenfassung:	A fast and simple procedure for simultaneous determination of nimesulide and paracetamol (acetaminophen) was carried out by batch injection analysis with multiple pulse amperometric detection (BIA-MPA). The purpose is achieved with a unique and simple injection of a sample aliquot (150μL) onto the unmodified boron-doped diamond (BDD) electrode immersed in a BIA system. The analytical characteristics of our proposed method include elevated analytical frequency (up to 46 injections per hour), high stability (RSD
