PMI
The aerosols are generated on a linear smoking machine and collected using Cambridge filter pad (CFP) followed by two micro impingers at 0 °C and -70 °C respectively, filled with 10 mL of methanol. The content of the CFP is then combined and extracted with the content of the impingers and delivered to the analytical laboratory. After filtration, the internal standards are added to the samples. The extracts are then analyzed by Gas Chromatography with Mass Spectrometry detection (GC-MS) using a column DB-WAXETR, 30 m x 0.25 mm ID x 0.5 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. 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.
