Alcohol-based hand sanitizers are typically prepared with isopropyl alcohol, or a form of denatured ethanol, which is the major component of the mixture. The concentration of the alcohol determines how effective the sanitizer is, and it must meet regulatory guidelines. For accurate results with excellent stability for samples containing high level of water-alcohol mixes, Agilent’s DB-624 UI has proven to effectively resolve IPA and EtOH as well as fusel oils and acetaldehyde if that analysis is required. The DB-WAX column has also shown to have a positive impact on the quantification of alcohols in alcohol-based hand sanitizers.
