室內污染監測用(yong)微量氣體采(cai)樣器(qi)S-21
目前(qian)的(de)(de)甲醛的(de)(de)濃度(du)測定(ding)方法(fa)一般(ban)是采用吸光(guang)(guang)光(guang)(guang)度(du)法(fa)或是HPLC法(fa)。但這需要昂貴的(de)(de)儀(yi)器、相(xiang)應的(de)(de)知識和熟練的(de)(de)操作。而(er)簡易測定(ding)法(fa)卻(que)無法(fa)測定(ding)室(shi)(shi)內微量的(de)(de)甲醛含量。新開(kai)發的(de)(de)檢(jian)知管，已經能夠測定(ding)0.01～1.2ppm的(de)(de)濃度(du)范圍，*WHO提(ti)出的(de)(de)室(shi)(shi)內環(huan)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(jia)醛濃度的測量(liang)，是zui常用(yong)的工(gong)作方法或(huo)absorptiometric高效(xiao)液相(xiang)色譜（高效(xiao)液相(xiang)色譜）方法。
但是，這些方法(fa)需要昂(ang)貴的(de)設備，知識和經驗。
此外，檢(jian)測(ce)(ce)管(guan)法(fa)是一(yi)種簡單有效的測(ce)(ce)量(liang)，到(dao)這一(yi)天(tian)，未能探(tan)測(ce)(ce)和跟蹤測(ce)(ce)量(liang)的室內甲醛污(wu)染(ran)程度的數額。
與(yu)空氣采樣器的S - 21，這個(ge)新(xin)開發的探測器能夠(gou)管內(nei)的范圍0.01 - 1.2ppm測量。它涵蓋了(le)室內(nei)環境(jing)建議(yi)值由世衛(wei)組織，這是(shi)0.1mg/m3（0.08ppm 30分(fen)鐘(zhong)平均）。
