室內污染監(jiān)測用微量氣體采樣器S-21
目前的甲醛的濃度測定方法一般是采用吸光光度法或是HPLC法。但這需要昂貴的儀器、相應的知識和熟練的操作。而簡易測定法卻無法測定室內微量的甲醛含量。新開發(fā)的檢知管，已經能夠測定0.01～1.2ppm的濃度范圍，*WHO提出的室內環(huán)境推薦值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，甲醛濃度的測量，是zui常用的工作方法或absorptiometric高效液相色譜（高效液相色譜）方法。
但是，這些方法需要昂貴的設備，知識和經驗。
此外，檢測管法是一種簡單有效的測量，到這一天，未能探測和跟蹤測量的室內甲醛污染程度的數(shù)額。
與空氣采樣器的S - 21，這個新開發(fā)的探測器能夠管內的范圍0.01 - 1.2ppm測量。它涵蓋了室內環(huán)境建議值由世衛(wèi)組織，這是0.1mg/m3（0.08ppm 30分鐘平均）。
