目的探讨采集氨的新方法方法采用扩散法将空气中氨采集在磷酸—甘油浸渍的无纺布吸收层上。结果采样速率为（１３７．６±８．４）ｍｌ／ｍｉｎ，与动力采样法现场对比测定，总不确定度为±１９．３％。结论采样器体积小、无噪声、操作方便，适于个体接触量与室内空气污染监测。
Objective To explore a new method for collecting ammonia by diffusion method to collect the air ammonia in the phosphate - glycerin impregnated non - woven absorbent layer. Results The sampling rate was (137.6 ± 8.4) ml / min, which was compared with the dynamic sampling method in the field. The total uncertainty was ± 19.3%. Conclusion The sampler is compact, noise-free and easy to operate. It is suitable for monitoring individual exposure and indoor air pollution.
