，但dan是shi有you時shi儀yi器qi自zi檢jian也ye許xu是shi已yi經jing通tong過guo了le，但dan是shi有you些xie儀yi器qi部bu分fen還hai是shi需xu要yao進jin行xing檢jian查zha：

1、光譜儀部分：看燈的負高壓是否處於正常範圍（一般是450~650v）
，如(ru)果(guo)突(tu)然(ran)發(fa)現(xian)負(fu)高(gao)壓(ya)特(te)高(gao)
，估(gu)計(ji)你(ni)就(jiu)要(yao)檢(jian)查(zha)光(guang)路(lu)了(le)
，看(kan)是(shi)否(fou)有(you)異(yi)物(wu)擋(dang)住(zhu)了(le)光(guang)路(lu)，鏡(jing)片(pian)是(shi)否(fou)有(you)起(qi)霧(wu)結(jie)冰(bing)。此(ci)時(shi)，就(jiu)需(xu)要(yao)用(yong)擦(ca)鏡(jing)紙(zhi)或(huo)者(zhe)吹(chui)風(feng)機(ji)吹(chui)幹(gan)，同(tong)時(shi)檢(jian)查(zha)環(huan)境(jing)溫(wen)濕(shi)度(du)是(shi)否(fou)達(da)標(biao)。

2、自動進樣器：首(shou)先(xian)，觀(guan)察(cha)自(zi)動(dong)進(jin)樣(yang)器(qi)管(guan)路(lu)是(shi)否(fou)出(chu)現(xian)異(yi)常(chang)，有(you)時(shi)一(yi)個(ge)晚(wan)上(shang)或(huo)者(zhe)是(shi)更(geng)久(jiu)時(shi)間(jian)不(bu)用(yong)

，溶(rong)液(ye)會(hui)在(zai)自(zi)動(dong)進(jin)樣(yang)器(qi)的(de)毛(mao)細(xi)管(guan)中(zhong)蒸(zheng)發(fa)結(jie)晶(jing)
，導(dao)致(zhi)自(zi)動(dong)進(jin)樣(yang)器(qi)堵(du)塞(sai)，或(huo)者(zhe)是(shi)管(guan)路(lu)不(bu)流(liu)暢(chang)。此(ci)時(shi)，在(zai)清(qing)洗(xi)過(guo)程(cheng)中(zhong)，儀(yi)器(qi)毛(mao)細(xi)管(guan)出(chu)水(shui)滴(di)的(de)速(su)度(du)會(hui)很(hen)慢(man)。或(huo)者(zhe)是(shi)吸(xi)水(shui)也(ye)會(hui)有(you)延(yan)遲(chi)現(xian)象(xiang)。看(kan)是(shi)否(fou)能(neng)夠(gou)準(zhun)確(que)地(di)將(jiang)溶(rong)液(ye)注(zhu)入(ru)到(dao)石(shi)墨(mo)管(guan)中(zhong)
，同(tong)時(shi)也(ye)要(yao)注(zhu)意(yi)檢(jian)查(zha)清(qing)洗(xi)進(jin)樣(yang)毛(mao)細(xi)管(guan)
，是(shi)否(fou)掛(gua)水(shui)珠(zhu)

，如(ru)果(guo)有(you)，可(ke)以(yi)用(yong)酒(jiu)精(jing)或(huo)者(zhe)是(shi)稀(xi)硝(xiao)酸(suan)擦(ca)洗(xi)。接(jie)著(zhe)，檢(jian)查(zha)冷(leng)卻(que)循(xun)環(huan)水(shui)，看(kan)壓(ya)力(li)是(shi)否(fou)在(zai)許(xu)可(ke)範(fan)圍(wei)之(zhi)內(nei)。

正確的儀器使用方法和及時的儀器維護是延長儀器壽命、保證儀器正常運轉的有效途徑之一。

石墨爐的維護在石墨爐膛部分，因為裏麵是加熱高溫-diwenlengqueyigexunhuanguocheng。tongshi，limianhaiyouhaiyuanxingqiangdeshimochanshengjitan

自動進樣器也是維護的重點對象，石墨爐報出數據的精密度低，跟進樣量少（10―30ul）youhendaguanxi。qizhongdemaoxiguandaochangnianyongzhengliushuizuoweiqingxiye
