Comparison of the cerulean e-cigarette pressure drop testing instrument to the ces 508 cigarette pressure drop and ventilation tester unit for electronic cigarettes, conventional tobacco burning cigarettes, and filter tips
The pressure drop or “resistance to draw” of cigarettes and cigarette-like products is a prominent experience for consumers. This poster is a comparison of two commercial instruments with different approaches to measuring pressure drop. The instruments compared are the Cerulean EPD100 e-cigarette testing instrument and the CES 508 cigarette pressure drop and ventilation tester. The design of the two test units differs significantly as the Cerulean unit forces air out through the test article, whereas the CES 508 instrument draws air through the test article. The comparison was made using samples of commercially-available electronic cigarettes (e-cigs), conventional tobacco-burning cigarettes, and filter tips. Overall, both test units provided comparable results over a range up to 200-mm H2O pressure drop. This poster presents the correlation and bias between the two different unit designs. The findings of this study demonstrate that conventional tobacco burning products and filter tips exhibit very low variability from unit to unit. The variation between units for electronic cigarettes is generally greater, presumably due to the hand-made nature of e-cigs compared to conventional machine-made cigarettes and filter tips.
