一种便携式有毒气体被动采样检测装置的研制

Study on a novel portable passive sampler and detector

以甲醛作为目标物,提出了一种基于扩散原理的具有大面积表面暴露的快速被动采样器及快速测定装置。该采样器不要求任何辅助采样泵使用该采样器研发的快速测定装置适用于现场气体样品的采集与测定。

Using formaldehyde as a target object, a simple detector and a passive sampler with the character of large specific surface area based on a gas molecular diffusion theory were developed. The synchronous detector companied with the passive sampler could realize fast sampling and real time detection on the spot, which was also simple, inexpensive and convenient.
