摘　　要：该文通过对采用便携式高温催化氧化非甲烷总烃测试仪现场测定涉挥发性有机物(VOCs)排放重点行业企业固定污染源废气中的非甲烷总烃,与VOCs废气样品经气袋采集返回实验室采用传统分析方法所获得的数据进行比较,得出便携式非甲烷总烃测定仪可更加准确、实时地反映固定污染源中挥发性有机废气排放情况。同时可为VOCs排放企业废气中挥发性有机物处理设施的选型进行科学指导,从源头上控制VOCs的排放。Determining NMHC in stationary sources involving major VOCs emitting industries with portable catalytic oxidation at high temperature-FID on site is described in this paper.Which is compared with the gas sample sampled and saved in plastic then measured by traditional GC-FID in the lab.The result shows that the portable instrument can accurately report the VOCs emission situation of stacks in real time.At the same time enterprises can be guided to select proper pollution control equipment for VOCs,so that VOCs emission can be controlled from origin.
