空心陰極燈 性能檢驗(yàn)方法

發(fā)布時(shí)間:2008/8/25點(diǎn)擊次數(shù):3866

在原子吸收分析中,空心陰極燈的性能直接影響分析結(jié)果,因此檢查燈的質(zhì)量是原子吸收分析中的一項(xiàng)重要工作,用已檢驗(yàn)合格的原子吸收光譜儀對(duì)空心陰極燈的性能進(jìn)行系列檢測(cè),光譜帶寬0.2nm,量程擴(kuò)展10倍,在原子化器未工作狀況下,點(diǎn)亮待檢測(cè)的空心陰極燈,進(jìn)行以下檢查:
    1.
起輝性能檢查
     
按空心陰極燈生產(chǎn)廠商規(guī)定的電流,通電后空心陰極燈應(yīng)能立即起輝,且發(fā)光點(diǎn)集中在空心陰極燈內(nèi),陽(yáng)極區(qū)不得出現(xiàn)輝光。
    2.
穩(wěn)定性檢查
