加热卷烟气溶胶捕集及其总水分的测定
Aerosol trapping and determination of total moisture in heated tobacco products
摘要
Abstract
[Objective]To accurately determine the total moisture content in heated tobacco product aerosol.[Methods]A two-stage trapping system combining a Cambridge filter with a granular CaCl2 tube was established for aerosol collection.The particulate-phase moisture captured on the Cambridge filter was analyzed by GC/TCD,while the gaseous-phase moisture was determined gravimetrically.Total aerosol moisture was calculated as the sum of particulate-phase and gaseous-phase moisture.[Results]The results showed that:1)A trapping tube filled with 4.0 g of granular CaCl2 met the requirement for trapping gaseous-phase moisture from up to four heated cigarettes.The measured gaseous-phase moisture exceeded 15 mg/cig,accounting for approximately 35%of total aerosol moisture in the experimental HTP samples.2)The intra-day relative standard deviations(RSDs)for the particulate-phase collection mass on the Cambridge filter,the gaseous-phase collection mass in the CaCl2 tube,and the total aerosol collected mass(ACM)were all within 4.46%,and the inter-day RSDs were within 5.17%,demonstrating good repeatability.3)Puff-by-puff release analysis showed that the proportion of gaseous-phase moisture in total moisture increased with puff number,rising from 27.06%in the first puff to 51.20%in the 10th puff.4)Sample test results indicated that ventilation rate and cigarette moisture content both influenced the release of water,nicotine,and other aerosol constituents.[Conclusion]This method enables complete moisture trapping in heated tobacco product aerosol and addresses the previous limitation of neglecting gaseous-phase water.It provides an effective means for thermal management and product quality evaluation of heated tobacco products.关键词
