Expanding on the initial study conducted in 2013 that establish a base line of effects on TPM yields of various e-cigarette designs with varied puff shape, duration, volume and interval. The latest investigation identifies how six different e-cigarette brands and their designs react under a varied number of smoking parameter variations, and how the magnitude of change can be as dependent on the design of the e-cigarette design as it can be on the magnitude of the smoke parameter change.

The resulting data provides an insight in to how a single set of smoking parameters can product a wide variation of TPM yields for these none homogenous product designs of apparently similar products.

As a baseline delivery component TPM yield is used to compare the effects of the varied smoking parameters on the varied e-cigarette designs. A further observation is made with the inclusion of a comparison between the duration of the actual vapor production phase versus the duration of the puffing duration.

In conclusion a set of smoking parameters is established as a base line for delivery testing of e-cigarettes with a potential method of verification of the e-cigarette’s completion of the puffing method.
