1. DETERMINAÇÃO RÁPIDA E SIMULTÂNEA DE PROPIFENAZONA, PARACETAMOL E CAFEÍNA UTILIZANDO ANÁLISE POR INJEÇÃO EM BATELADA COM DETECÇÃO AMPEROMÉTRICA
A fast and simple procedure for simultaneous determination of propyphenazone (PRO), paracetamol (PAR) and caffeine (CAF) was performed using batch injection analysis with multiple pulse amperometric detection (BIA-MPA). Three potentials pulses were selected for the analysis: +0.90 V/50 ms: only PAR was oxidized; +1.20 V/50 ms: oxidation of PAR and PRO withou

2. AMPEROMETRIC DETERMINATION OF 8-CHLOROTHEOPHYLLINE, CAFFEINE, AND DIPHENHYDRAMINE IN A SINGLE RUN
A simple method for simultaneous determination of 8-chlorotheophylline (CTP), caffeine (CAF), and diphenhydramine (DIP) using batch-injection analysis with multiple pulse amperometric detection (BIA-MPA) is reported. A sequence of three potential pulses (+1.10 V, +1.40 V, and +1.70 V) was applied to the boron-doped diamond working electrode with the acquisit

3. Determinação de etanol e metanol em álcool combustível e gasolina empregando métodos eletroanalíticos
In this present work two analytical procedures are presented. The first deals with the simultaneous determination of ethanol (EtOH) and methanol (MetOH) in fuel ethanol samples using Cyclic Voltammetry (CV) and the second, the determination of EtOH in fuel ethanol and gasohol using Batch Injection Analysis with Multiple Pulses Amperometric detection (BIA-MPA

4. Determinação simultânea de ácido ascórbico e ácido acetilsalicílico usando análise por injeção em fluxo com detecção amperométrica pulsada
A simple flow system with multiple pulse amperometric detection using a single working electrode is proposed for simultaneous determination of ascorbic (AA) and acetylsalicylic (AAS) acids in pharmaceutical formulations. The procedure is based on application of two potential pulses: 0.90 V/50 ms: oxidation and determination of AA without the interference of
