Hand sanitizers are used daily to sanitize the hands of healthcare workers and essential workers, as well as the general population. After the COVID-19 pandemic was declared in 2020, sanitization has become more important than ever and is used to clean hands and kill bacteria. A common ingredient in hand sanitizers is ethanol, which is effective at killing bacteria. However, due to its close relation, methanol, which is poisonous to consume and be absorbed into the skin, can sometimes be found in these products. This project focuses on analyzing hand sanitizer with the technique solid phase microextraction (SPME) with an Agilent Intuvo Single Quadruple 5977B Gas Chromatograph Mass Spectrometer. SPME is an extraction technique that uses a polymer coated fiber to absorb volatile organic compounds which are then injected into a gas chromatograph mass spectrometer (GC-MS). This allows for the accurate analysis of small volatile organic compounds as in hand sanitizers and for the separation of methanol and ethanol to be documented. This project will be used to determine whether these hand sanitizer products contain any substances that may be harmful to the population, including methanol.
