NCG-1冷原子吸收測汞儀 產品信息

 

一、序言

汞及其化合物的*性質,在科研和生產領域得到廣泛應用,但也帶來了環境污染,并對生物造成了危害因此汞的監測得到國家很大的重視,并規定了空氣中汞蒸汽濃度在居住區不得超過0.0003mg/m3,工業生產區不得超過0.01mg/m3,生活飲用水含汞量不超過1ug/L(1ppb)。近年來由于此項工作的不斷發展,微量汞的分析方法也在不斷改進,對測汞儀的全性能要求也越來越高。鑒于目前冷原子吸收法仍為一種主要的測汞手段,所以本廠對國內現有的測汞儀進行了比較,在此基礎上研制生產了NCG—1型冷原子吸收測汞儀,該儀器極大改善了漂移和噪聲,提高了靈敏度和精確度,具有數保持功能。

1測量范圍:0-1000g/ml(高于10ng/ml稀釋)

2、檢出下限:≤0.05ng/ml(0.05ppb) 

3、穩定性:零點漂移:1%(F.S)/4h

4線性相關系數:R≥0.995 

5、變異系數:cv5%

6、數顯保持誤差:1%/min

7、流量調節范圍:0-2.5L/min 

8、正常工作條件:a、溫度:5-40℃ 

b、濕度:85%

c、供電:220V±10%  50±0.5HZ

9、儀器外形尺寸:430×420×165mm3
