Quaternary Ammonium Compounds (QAC)

-Direct Binary Complex Method (Method 8337)


The reagents buffer the sample to an acidic pH and include a masking agent to remove potential interferences. The indicator reacts with quaternary ammonium compounds in the sample and forms a pale pink to vivid purple color. This test is applicable to monitor quaternary ammonium compounds in swimming pools and cooling towers. The measurement wavelength is 575 nm.
