Fig. 5From: Application of dosimetry tools for the assessment of e-cigarette aerosol and cigarette smoke generated on two different in vitro exposure systems Boxplot showing QCM determined aerosol particle deposition from a cigarette and an e-cigarette on the RM20S (top). Deposited nicotine concentration from the washed QCM for a cigarette and an e-cigarette on the RM20S (bottom). Mass and nicotine values are the mean of three QCMs per chamber and three replicate experiments per product and dilution. Asterisks denote single data point outliers, as determined by MinitabBack to article page
