Chemical determination of electronic cigarette's aerosol and gas phase
Summary:
The current thesis was developed in the Laboratory of Analytical Chemistry of University of Athens. The purpose of this thesis was the development of analytical methods for the quality control of commercial electronic liquid cigarettes for harmful chemical compounds such as polycyclic aromatic hydrocarbons (PAHs) and BTEX volatile organic compounds (benzene, toluene, ethylbenzene, xylenes). Especially, the aerosol of electronic cigarette was studied and analyzed for polycyclic aromatic hydrocarbons (PAHs), while the gas phase for BTEX and volatile organic compounds. An array was created, using an electronic cigarette, a pump, a set of teflon tubes and plastic tips, where the aerosol of electronic cigarette was condensed into liquid. Additionally, a solenoid of activated carbon adsorbent material was connected to the same device. The liquefied steam after pretreatment was analyzed for polycyclic aromatic hydrocarbons, while the charcoal was analyzed for BTEX volatile organic compounds. The determination of these compounds was carried out by gas chromatography coupled to mass spectrometry (GC-MS). Furthermore, chemical determination was performed in aerosol and gas phase samples using GC/TOFMS.
