Application Note: UPLC Analysis of Benzalkonium Chloride (BAC) in Consumer Products using ACQUITY UPLC CSH C18
8 May 2013

This application note presents an alternative to the USP method for the quantitation of Benzalkonium Chloride (BAC). The analysis of BAC is performed with a Charged Surface Hybrid (CSH) C18 stationary phase under UPLC® conditions. Results demonstrate improved peak shapes with significant reductions in both analysis time and solvent consumption.
