Coulometry

Coulometry is an electrochemical analysis method where the quantity of analyte is determined by measuring the total charge passed during a complete oxidation or reduction reaction.

This precise technique is often used for trace analysis and purity testing.

• Measures total electric charge for quantitative results
• Highly accurate for small sample sizes
• Applications include water content (Karl Fischer), chlorine, and metal ion determination
• Available in dedicated benchtop analyzers
