SIMULTANEOUS VOLTAMMETRIC DETERMINATION OF AMLODIPINE BESYLATE AND HYDROCHLOROTHIAZIDE IN SYNTHETIC URINE SAMPLES USING A BORON-DOPED DIAMOND ELECTRODE

Simultaneous Determination of Paracetamol and Ibuprofen in Pharmaceutical Samples by Differential Pulse Voltammetry Using a Boron-Doped Diamond Electrode

O presente trabalho apresenta uma metodologia simples, rápida e de baixo custo para determinação simultânea de paracetamol (PC) e ibuprofeno (IB) em formulações farmacêuticas por voltametria de pulso diferencial usando eletrodo de diamante dopado com boro (BDD). Os analitos apresentaram picos de oxidação definidos em 0,85 V para o PC e 1,72 V para o IB (vs. Ag/AgCl) sobre o eletrodo de trabalho...

Simultaneous Voltammetric Detection of Carbaryl and Paraquat Pesticides on Graphene-Modified Boron-Doped Diamond Electrode

Monitoring of pesticide residues in food, beverages, and the environment requires fast, versatile, and sensitive analyzing methods. Direct electrochemical detection of pesticides could represent an efficient solution. Adequate electrode material, electrochemical technique, and optimal operation parameters define the detection method for practical application. In this study, cyclic voltammetric ...

Development of Conductive Boron-Doped Diamond Electrode: A microscopic, Spectroscopic, and Voltammetric Study

Building on diamond characteristics such as hardness, chemical inertness and low electron emission threshold voltage, the current microscopic, spectroscopic and voltammetric investigations are directed towards improving the properties of electrode coating materials for their future use in clinical studies of deep brain stimulation via fast-scan cyclic voltammetry (FSCV). In this study we combin...

Simultaneous Detection of Monoamine and Purine Molecules using HPLC with a Boron-Doped Diamond Electrode

Most biochemical analyses typically examine molecules from the same neurochemical family, like dopamine and serotonin (monoamines), and GABA and glutamate (amino acids). In this present study, two different families, monoamines and purines, are being investigated using high-performance liquid chromatography (HPLC) with a boron-doped diamond (BDD) electrode. There is considerable data demonstrat...
