    Method development and validation for the quantification of metals in liquids and aerosol of e-cigarettes

    OTTE S.; NOWAK S.; INTORP M.
    Imperial Tobacco Group, Reemtsma Cigarettenfabriken GmbH, Biological Labs Hamburg, Hamburg, Germany
    Due to the rapidly increasing popularity of e-cigarettes, several studies were carried out to characterise this new type of product. E-cigarettes produce a condensation aerosol by heating an e-liquid invariably consisting of a mixture of propylene glycol ...
