Quaternary ammonium salts (QAC) test strips provide rapid colorimetric determination of quaternary ammonium biocide concentrations in aqueous solutions. These analytical test strips utilize ion-pairing chemistry between quaternary ammonium compounds and pH indicator dyes to produce concentration-dependent color changes. The test strips are designed for field and laboratory monitoring of sanitizer efficacy, particularly benzalkonium chloride solutions at standard 200 PPM concentrations.

The strips employ acidobasic indicators in a buffered microenvironment on the test pad, creating selective response to quaternary ammonium compounds rather than solution pH. This approach enables reliable quantification of QAC levels for quality control in sanitization protocols where precise biocide concentration is critical for antimicrobial effectiveness.
