Analysis of 12 polycyclic aromatic hydrocarbons in THS aerosol
PMI
The aerosol samples are generated with a linear smoking machine and collected on a Cambridge filter pad. Polycyclic aromatic hydrocarbons (PAHs) are then extracted with hexane after addition of internal standards. The aerosol extract undergoes a two steps solid-phase extraction (SPE) clean-up procedure in order to remove some matrix co-extracted organic compounds that reduce the performance of the chromatographic system and affect the accuracy of PAHs determination. The resulting extracts are analyzed by Gas Chromatography with Electron Impact Mass Spectrometry (GCEI-MS). The GC system is equipped with a column DB-17MS column, 30 m x 0.25 mm ID x 0.15 μm (film thickness). Results are expressed as ng/item for the Tobacco Heating System (THS), referred to as Platform 1 (P1) in the method.

PMIScience.com is operated by Philip Morris International for the purpose of publishing and disseminating scientific information about Philip Morris International’s efforts to develop and assess products that have the potential to reduce individual risk and population harm associated with tobacco use. This site is for use by scientists, the public health and regulatory communities, and other stakeholders with an interest in tobacco policy. The purpose of this site is not for advertising or marketing. It is not intended for use by consumers.
Reduced Risk Products ("RRPs”) is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking. PMI has a range of RRPs in various stages of development, scientific assessment and commercialization. Our RRPs are smoke-free products that produce an aerosol that contains far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
