抄録

For the purpose of the quantitative evaluation of tobacco smoke exposure, a convenient personal monitoring system of nicotine specific for tobacco smoke was developed.<BR>Nicotine was collected by passing ambient air through a sampler tube (12cm long, 5mm i. d.) at a flow rate of 40ml/min for a maximum period of 8 hours with a personal pump. The sampler tube contains 450mg of Chromosorb W (AW-DMCS, 30-60mesh) coated with 10wt% of Silicon OV-17. After the completion of sampling period, the sampler tube was placed in a cylindrical furnace heated at 280°C and connected with the injection port of a gas chromatograph via an injection needle. Passing the carrier gas through the tube, nicotine was transported quantitatively onto a column.<BR>Amounts of passive inhalation of nicotine in some places were estimated to be in the range of 5-37μg for 8 hours. The valid range of the determination of ambient nicotine was 5-500ng per sampler tube.<BR>The principal advantages of the personal monitoring system can be summarized as follows:<BR>(1) The sensitivity is about 10-1000 times as high as those of ordinary methods utilizing wet process.<BR>(2) The sampler is compact, portable, and can be used repeatedly.<BR>(3) The direct thermal desorption of nicotine in the carrier gas flow saves much time and simplifies the analytical processes.<BR>(4) Since no liquid is involved, analytical sample is free from possible contamination by nicotine from glass ware, solvent, etc.
