    Summary

    The aerosols are generated on a linear smoking machine and collected using Cambridge filter pad (CFP) followed by two impingers filled with 5 mL of toluene. After the smoking process, the CFP is discarded and the contents of the two impingers are combined and delivered to the analytical laboratory for addition of internal standard and analysis.

    The extracts are analyzed by Gas Chromatography with Mass Spectrometry detection (GC-MS) using a column Agilent Pora Bond Q 25 m x 0.25 mm ID x 3 µm film thickness. Results are expressed as µg/item for the Tobacco Heating System (THS), referred to as Platform 1 (P1) in the method.

    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. All of our RRPs are smoke-free products that deliver nicotine with far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
