This study assessed the feasibility of using portable infrared and handheld Raman devices for the rapid screening of alcohol-based gel hand sanitizers to detect potential adulteration or misbranding. Alcohol potency was estimated by analyzing the concentration-dependent hydrogen bond-induced peak sh...
