The article shows the successfull qualification of the Vitrocell VC10 smoking robot. The robot was used to  expose bacterial cells to cigarette whole smoke generated from 3R4F reference cigarettes and Eclipse cigarettes. A comparison was made between whole smoke from a tobacco heating and a combustible cigarette.

The study shows an assessment of VC1 aerosol generation that was conducted by measuring puff-by-puff in vitro nicotine concentration of 3R4F cigarettes (ISO and HCI regimes), e-cigarette (CRM81 puffing profile), and THP (HCIm regime). The aerosols were applied to in vitro or ex vivo cellular and tissue systems that model the respiratory tract, such as reconstructed human airways (RHuA), which are grown at the air–liquid interface (ALI). Additionally a comparison between the Vitrocell VC1 (U.S. Laboratory) and the VC10 (UK Laboratory) Smoking Robot was done.
