摘要
ＡＦＳ－ ２２０１ 型双道原子荧光光度计原子化器氢焰易受外界环境空气流动的影响产生波动，造成仪器样品测试的精密度不稳定而影响仪器的正常使用。通过对原子化器氢焰波动原因的分析，提出了减小外界环境空气流动影响的方法，对仪器原子化器烟囱的结构进行了改进，使仪器在不同环境条件下样品测试的ＲＳＤ控制在５ ％ 以下。
AFS-2201 atomic fluorescent photometer is not used in gear because flutuating of hydrogen buring of AFS-2201 atomic fluorescent photometer affect on degree of precision for flowing air in enviroment. The mothed reduced effect on degree of precision for flutating of hydrogen buring is put forward by analysing causes of flutuating of hydrogen buring of AFS-2201 atomic fluoresscent photometer. RSD of testing in defferent codition is controled among 5% by improved on structure of chimney of AFS-2201 atomic fluorescent photometer.
