Hand Sanitizer | Composition Analysis and Quality Assessment


           World Health Organization (WHO) recommends the practice of good hand hygiene as one of the
           basic protective measures against COVID-19. This includes washing hands with soap and water or
           using an alcohol-based hand sanitizer. U.S. CDC have recommended sanitizers with 60–95% alco-

           hol as the most effective composition of sanitizers.

          Additionally, with concerns over product fraud or fake substances used in the manufacturing of
          sanitizers, the analysis of key active ingredients, such as alcohol, in sanitizers is crucial. Shimadzu
          FTIR IRSpirit  and GC Nexis-2030 provide ready to use simple methodology for the measurement
                      TM
          of ethanol and isopropyl alcohol (IPA) in hand sanitizers.

                                                                   TM
                                               Provides a simple methodology Drop and Click workflow
                                               for the quantitation of ethanol or IPA in sanitizers
                                               The Drop and Click workflow enables:
