This workshop will be presented in two parts. The first section will focus on the basic design and construction of both typical disposable/rechargeable devices and selected advanced personnel vaporizers. Topics will include cartomizer and atomizer construction, battery voltage and device yield profiles. This section of the workshop will include a “hands-on” session in which workshop participants will be able to collect e-cigarette aerosol with an analytical smoking machine. The second section will focus on e-liquids, including product stewardship, analytical techniques, and comparisons of tobacco-like and exotic flavors.
