Tetraethylammonium Bromide (TEAB), identified by its CAS number 71-91-0, is a cornerstone chemical for precise electrochemical analyses, particularly in polarographic applications. As a key polarographic reagent, TEAB is instrumental in enhancing the sensitivity, accuracy, and reliability of measurements involving various metal ions and other electroactive species. For analytical laboratories and research institutions, sourcing high-purity TEAB from a dependable polarographic reagent manufacturer is non-negotiable.

Polarography is an electrochemical technique that relies on measuring the current-voltage relationship of a solution containing electroactive species. The presence of TEAB in the supporting electrolyte of a polarographic analysis plays a crucial role. It acts as a source of supporting electrolyte ions, increasing the solution's conductivity and thereby reducing iR drop, which can distort voltammograms. More importantly, TEAB can influence the kinetics of electrode reactions and form complexes with target analytes, leading to sharper and more defined polarographic waves. This amplification effect is vital for detecting low concentrations of analytes, making trace analysis possible.

TEAB is particularly recognized for its utility in the determination of precious metals like gold, iridium, palladium, rhodium, and ruthenium. In these analyses, TEAB can complex with the metal ions, often shifting their reduction potentials to more accessible regions or improving the peak shape for accurate quantification. This makes it an indispensable tool for industries ranging from mining and metallurgy to environmental testing and precious metals refining.
