Peracetic Acid (PAA) Analysis by Potentiometric Titration | Food & Disinfectant Applications

Application Overview

This application note describes the fractional determination of hydrogen peroxide and peracetic acid in disinfectant solutions using automatic potentiometric titration. These oxidizing agents are widely used in food and beverage processing for clean-in-place (CIP) systems and sanitation programs, where accurate concentration control is essential for effective hygiene and process safety. Used by food and pharmaceutical manufacturers for disinfectant and sanitation control.

Analytical Method

The method employs automatic potentiometric titration to selectively determine hydrogen peroxide and peracetic acid in mixed disinfectant formulations. Automated endpoint detection enables reliable differentiation between oxidants, improves repeatability, and reduces operator-dependent variability in routine quality control testing.

Sample Type

  • Disinfectant solutions

  • Peracetic acid / hydrogen peroxide mixtures

  • CIP sanitation chemicals

Representative Application Data
