用塑料袋采集呼气中的有机气体,易使样品逸漏和吸附损失。用活性炭采集空气中氯乙烯已有报道。本文采用活性炭采集呼气中氯乙烯,通过肺量计计量呼气量,用自制热解吸炉解吸之,气相色谱法测定,获得良好结果,其方法适宜推广使用。实验与方法一、测定原理呼气中氯乙烯用活性炭管采集,经热解吸后, Use plastic bags to collect expiratory organic gases, easy to make samples leak and adsorption loss. The use of activated carbon to capture vinyl chloride in the air has been reported. In this paper, the use of activated carbon to collect expiratory vinyl chloride, breath expiratory volume measured by spirometry, desorption with a homemade pyrolysis furnace, gas chromatography, good results, the method is suitable for promotion. Experiment and method First, the determination principle Vinyl chloride in the expiration with activated carbon tube collection, after thermal desorption,
