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.
IRSpirit with QATR –S
TM
Provides a simple methodology Drop and Click workflow
for the quantitation of ethanol or IPA in sanitizers
The Drop and Click workflow enables:
• Fast results, under 1 min analysis time
• No or minimal sample preparation required
• Excellent data quality and reproducibility
• Low running cost and minimal instrument maintenance
