This study investigated the in vitro mutagenicity of e-cigarettes and designed a study to deliver e-cigarette aerosol on an undiluted per puff basis under extreme testing conditions, using the Ames assay across a broader range of bacterial tester strains. The Vitrocell VC 10 smoking robot, previously used to generate and dilute cigarette smoke aerosols was modified to enable the testing of an undiluted e-cigarette aerosol.
