                      三氯乙烯Cl2C=CHCl氣體測毒管134SB TRICHLOROETHYLENE 0.2-36.8

                      簡要描述:

                      三氯乙烯Cl2C=CHCl氣體測毒管134SB TRICHLOROETHYLENE 0.2-36.8ppm,檢知管法(detectortubemethod)指用試劑浸泡過的載體顆粒裝在玻璃管中,當(dāng)被測空氣以一定速度抽過此管時,被測物質(zhì)與試劑發(fā)策顏色反應(yīng),然后根據(jù)顏色的深淺和色柱的長短,與標(biāo)準(zhǔn)色板或濃度標(biāo)尺進(jìn)行比較,從而作出定性和半定量的分析方法。所用載體應(yīng)具畝下列性能:(1)化學(xué)惰性,即不與被測物質(zhì)和試劑起反應(yīng);(2)質(zhì)地牢固,并能粉碎成一定大小的顆粒;(3)白色多孔或表面粗糙的固體物質(zhì)。

                      1. PERFORMANCE
                      1) Measuring range :1-16 ppm 0.2-3.2 ppm
                      Number of pump strokes 1(100ml) 4(400ml)
                      2) Sampling time :1.5 minutes/1 pump stroke
                      3) Detectable limit :0.1 ppm(400ml)
                      4) Shelf life :1 year (Necessary to store in a refrigerated place ; 0~10℃)
                      5) Operating temperature :0~40℃
                      6) Reading :Direct reading from the scale calibrated by 1 pump stroke
                      7) Colour change :Pale orange→Blueish purple
                      2. RELATIVE STANDARD DEVIATION
                      RSD-low:10% RSD-mid.:10% RSD-high:10%
                      3. CHEMICAL REACTION
                      By reacting with an Oxidizer, Hydrogen chloride is produced and PH indicator is discoloured.
