The aerosols are generated on a linear smoking machine and collected using Cambridge filter pad (CFP) followed by a micro impinger filled with 10 mL of cyclohexane with internal standard. The content of the CFP is then combined and exctracted with the content of the impinger and delivered to the analytical laboratory. Solid phase extraction is performed to clean-up the samples before analysis. The extracts are then analyzed by Gas Chromatography with Mass Spectrometry detection (GC-MS) using a column DB-17 MS 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.
