氧氮?dú)浞治鰞x的操作過程氧氮?dú)浞治鰞x可根據(jù)的用戶的要求定制。該分析儀配備兩個(gè)不同靈敏度的探測器,，在更多的應(yīng)用中保證了準(zhǔn)確度,。操作簡單而且安全。在樣品稱重以后,，樣品的重量數(shù)據(jù)通過電子界面?zhèn)鲗?dǎo)至相連的電腦中,，也可以在軟件界面中手動(dòng)輸入樣品的重量。樣品被放置在水平放置的爐子中的低溫區(qū)域。分析開始以后,，爐子開始向上轉(zhuǎn)動(dòng),，然后樣品逐漸落入加熱區(qū)。通過添加載體氣體氮?dú)?，氫氣被擴(kuò)散出來并且隨載體被傳導(dǎo)至一個(gè)高靈敏度的熱傳導(dǎo)測量池,。通常一次測量的時(shí)間在3到15分鐘之間,。在分析的過程中設(shè)備可以顯示測試信號(hào)和設(shè)備的參數(shù)，從信號(hào)的評估到結(jié)果在界面上的顯示全部自動(dòng)完成,；而測量數(shù)據(jù)則被傳導(dǎo)至LIMS（實(shí)驗(yàn)室信息管理系統(tǒng)）中,。無需過多的保養(yǎng)和維護(hù)，而除塵器和凈化管的維護(hù)工作也方便,。上海禹重實(shí)業(yè)有限公司致力于提供分析儀，有想法可以來我司咨詢,。

氧氮?dú)浞治鰞x的常見故障及解決方法：氧和氮空白值超過20,。這是由于氣流小,，不能將爐子中的空氣驅(qū)趕出去?？烧{(diào)節(jié)氣體流量,，調(diào)節(jié)載氣壓力在0.2~0.4MPa。接通儀器載氣,，放一個(gè)石墨坩堝在下電極上,，打開主電源開關(guān)，點(diǎn)擊軟件上的關(guān)爐按鈕,，關(guān)閉爐子并等待10s。調(diào)節(jié)流量調(diào)節(jié)器,，直到流量計(jì)a顯示為30L／h，打開爐子,。調(diào)節(jié)調(diào)節(jié)器直到流量計(jì)b顯示為50L／h，再次關(guān)閉爐子,。如果以上設(shè)置不穩(wěn)定,，則增加流量至100L／h，反復(fù)調(diào)節(jié)直至儀器穩(wěn)定,。上海禹重實(shí)業(yè)有限公司致力于提供分析儀，有想法的可以來電咨詢,！山東分析儀多少錢
