1. Plural of coulometry; analytical techniques that measure the quantity of electric charge (in coulombs) required to complete a chemical reaction, used to determine the amount of a substance in a sample.
Usage: technical; chemistry; analytical chemistry

Examples

• The laboratory uses coulometries to analyze the purity of metal samples.
• Different coulometries can be applied depending on whether the analyte is oxidizable or reducible.
• Coulometries provide accurate quantitative results by measuring the total charge passed during electrolysis.
• The researcher compared several coulometries to determine which method was most efficient for the analysis.
