目前(qian)的(de)(de)甲(jia)醛的(de)(de)濃度測(ce)定(ding)方法一般是(shi)采用(yong)吸光光度法或(huo)是(shi)HPLC法。但這需要(yao)昂貴的(de)(de)儀器、相應(ying)的(de)(de)知識(shi)和(he)熟(shu)練的(de)(de)操作。而簡易測(ce)定(ding)法卻無法測(ce)定(ding)室(shi)內(nei)微(wei)量的(de)(de)甲(jia)醛含(han)量。新開發的(de)(de)檢知管,已經能夠測(ce)定(ding)0.01~1.2ppm的(de)(de)濃度范圍,*WHO提出的(de)(de)室(shi)內(nei)環境推薦值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(mu)前,甲醛濃(nong)度的(de)測量(liang),是zui常用(yong)的(de)工作方法或absorptiometric高效液(ye)相(xiang)色譜(pu)(高效液(ye)相(xiang)色譜(pu))方法。
但是,這(zhe)些(xie)方法需要昂貴(gui)的設備,知識(shi)和經驗。
此外(wai),檢測管法是一(yi)種簡單有效的(de)(de)測量(liang),到這一(yi)天,未能探測和跟蹤測量(liang)的(de)(de)室內(nei)甲(jia)醛污(wu)染程度(du)的(de)(de)數額。
