酒精(乙醇)C2H5OH氣體檢測(cè)管104SA ETHYL ALCOHOL(ETHANOL)

簡(jiǎn)要描述:

酒精(乙醇)C2H5OH氣體檢測(cè)管104SA ETHYL ALCOHOL(ETHANOL)0.05-5.0%,當(dāng)被測(cè)氣體中含有硫化氫通過檢測(cè)管時(shí),與吸附在載體上的醋酸鉛產(chǎn)生棕褐色染色段,染色段長(zhǎng)度與硫化氫含量成正比例,測(cè)定不同氣體的檢測(cè)管其化學(xué)組成是不同的,檢測(cè)管的化學(xué)反應(yīng)原理與常用的化學(xué)分析反應(yīng)原理基本相同,檢測(cè)管法只是將化學(xué)分析中的所謂“液態(tài)反應(yīng)"轉(zhuǎn)移到固體表面上進(jìn)行的。
