Finally, the organic phase was subjected to extraction with 20 mL of 8N aqueous sodium hydroxide solution to obtain an aqueous phase. The aqueous phase was subjected to gas chromatographic analysis (Agilent GC-FID/TCD, GC: 7890B was used).
  • the amount in the smoke was determined by connecting a Cambridge filter to the mouth end of the smoking article and subjecting the article to a smoking test using a smoking machine. Specifically, smoking was performed automatically using an automatic smoking machine, and particulate matter in the tobacco smoke for each puff was collected with a Cambridge filter (CM-133, manufactured by Borgwaldt KC Inc.). After the smoking test, the Cambridge filter was shaken in 10 mL of methanol (special grade reagent, manufactured by Wako Pure Chemical Industries, Ltd.) to obtain an analytical sample. 1 ⁇ L of the obtained analytical sample was collected in a microsyringe and analyzed using a gas chromatograph analyzer (GC-FID/TCD, GC: 7890B, manufactured by Agilent).
