Significance: Historically, tobacco product emissions testing using smoking machines has largely focused on combustible products, such as cigarettes and cigars. However, the popularity of newer products, such as electronic cigarettes (e-cigarettes), has complicated emissions testing because the products' mouth-end geometries do not readily seal with existing smoking and vaping machines. The demand for emissions data on popularly used products has led to inefficient and non-standardised solutions, such as laboratories making their geometry-specific custom adaptors and/or employing flexible tubing, for each unique mouth-end geometry tested.

- Accurate characterization of tobacco product emissions is crucial for evaluating their health impacts, and a leak-tight seal is necessary for reliable data collection.
- A prototype universal smoking machine adaptor (USMA) was developed to work with various tobacco products, demonstrating effective sealing with different shapes and sizes.
- Testing showed that emissions measured with the USMA were consistent and precise, often outperforming other adaptors in repeatability and accuracy.
