FORMIC ACID

This test method uses ion chromatography and conductivity detection to monitor formic acid. Handle all hazardous chemicals in a fume hood. This is a modification of Method 7903 (Acids, inorganic) and revises Method S173. Formic acid is typically used as a preservative and an antibacterial agent in livestock feed. It′s also used to produce leather in the tanning and dyeing process.

Analysis Type (Application Method): Ion chromatography, conductivity
