砷化氫氣體檢測管 121U
砷化氫氣體檢測管 121U，砷化氫氣體檢測管 121U ARSINE AsH3 0.05-2ppm，日本光明理化工業(yè)株式會社從1947年開始，在氣體分析領(lǐng)域開拓了六十余年 , 形成了馳名于世的 ” 北川 ” 式氣體檢測管。氣體快速分析法 ” 北川 ” 的歷史就是日本檢測管的歷史 。目前是世界上*大的檢測管生產(chǎn)廠家，也是日本**家通過美國SEI的認證，歐盟的認證的檢測管廠家。公司不僅有ISO9001:2000的認證，還獲得了環(huán)境管理的ISO14001的認證。北川式手動氣體采集器AP-20 備有采氣完成指示計 , 可以清楚的判明采氣是否完成 . • 有專門截留玻璃的截留槽 , 以防止檢測管割尖時玻璃片飛濺 . • 有采氣容積為 50 毫升和 100 毫升的兩段式制動卡 . • 采氣器極為小巧 , 并有便于攜帶的皮具包 。
Tube No.121U
1. PERFORMANCE
1) Measuring range ：0.1-2.0 ppm 0.05-0.5 ppm
Number of pump strokes 1(100ml) 2(200ml)
2) Sampling time ：1 minute/1 pump stroke
3) Detectable limit ：0.02 ppm(200ml)
4) Shelf life ：2 years
5) Operating temperature ：0～40℃
6) Reading ：Although the scale of this tube is calibrated based on Phosphine at 1 pump
stroke, the sensitivity of Arsine is completely same.
7) Colour change ：Pale yellow→Pink
2. RELATIVE STANDARD DEVIATION
RSD-low：10％ RSD-mid.：10％ RSD-high：5％
3. CHEMICAL REACTION
By reacting with Mercury chloride(II), Hydrogen chloride is produced and PH indicator is discoloured.
AsH3＋HgCI2→As(HgCI)3＋HCI
4. CALIBRATION OF THE TUBE
STANDARD GAS CYLINDER METHOD

(NOTE)
This tube scale is calibrated based on Phosphine and the same scale is available for Arsine.
When the concentration is below 0.5 ppm , 2 pump strokes can be used to detemine the lower concentration.
Following formula is available for the actual concentration.
Actual concentration＝1/2×Reading value
