一、序言

汞及其化合物的*性質(zhì),在科研和生產(chǎn)領(lǐng)域得到廣泛應(yīng)用,但也帶來了環(huán)境污染,并對生物造成了危害因此汞的監(jiān)測得到國家很大的重視,并規(guī)定了空氣中汞蒸汽濃度在居住區(qū)不得超過0.0003mg/m3,工業(yè)生產(chǎn)區(qū)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(fā)展,微量汞的分析方法也在不斷改進(jìn),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(nèi)現(xiàn)有的測汞儀進(jìn)行了比較,在此基礎(chǔ)上研制生產(chǎn)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(shù)保持功能。

二、儀器的性能
