室内污染监测用微量气体采样器S-21
目前的甲醛的浓度测定方法一般是采用吸光光度法或是HPLC法。但这需要昂贵的仪器、相应的知识和熟练的操作。而简易测定法却无法测定室内微量的甲醛含量。新开发的检知管，已经能够测定0.01～1.2ppm的浓度范围，*WHO提出的室内环境推荐值0.1mg/m3（0.08ppm30min平均）。

Currently, measurements for concentration of formaldehyde is done most commonly by absorptiometric method or HPLC （high performance liquid chromatography） method.
However, these methods require expensive devices, knowledge and experience.
Furthermore, in detector tube method which is effective as a simple measurement, up to this date it had been impossible to detect and measure the trace amount of formaldehyde at the indoor pollution level.
With Air sampler S-21, this newly developed detector tube is capable of measuring within the range of 0.01 - 1.2ppm. And it covers the indoor environment suggested value by WHO, which is 0.1mg/m3 （0.08ppm 30min average）.
目前，甲醛浓度的测量，是zui常用的工作方法或absorptiometric高效液相色谱（高效液相色谱）方法。
但是，这些方法需要昂贵的设备，知识和经验。
此外，检测管法是一种简单有效的测量，到这一天，未能探测和跟踪测量的室内甲醛污染程度的数额。
与空气采样器的S - 21，这个新开发的探测器能够管内的范围0.01 - 1.2ppm测量。它涵盖了室内环境建议值由世卫组织，这是0.1mg/m3（0.08ppm 30分钟平均）。
