<p>紅外測油儀相比原有傳統(tǒng)的油類分析儀先取樣再以定性方式量測，時間長且無法及時得到測量數(shù)據(jù)。而大多數(shù)物質(zhì)的分子官能基能吸收紅外光，利用光譜能量的吸收與轉(zhuǎn)換很容易進行內(nèi)部成分的定性分析和定量計算。</p><p>主要應(yīng)用領(lǐng)域：紅外測油儀不僅適用于地表水、地下水、海水、生活用水和工業(yè)廢水等各種水體及土壤中石油類(礦物油)、動植物油及總油含量的監(jiān)測，同時也是煙氣(飲食行業(yè)油煙)含油量監(jiān)測國家標(biāo)準(zhǔn)推薦的儀器。此外，還可用于有機試劑純度檢測及含各種不同C-H鍵有機物總量和分量的測量。</p><p>　　初次運用紅外分光測油儀工作時需求留意哪些問題？</p><p>　　采用光度法特地測量水質(zhì)類和動植物油的實驗室儀器，采用磁力攪拌萃取的方式用化碳萃取水中的油類物質(zhì)，然后運用疏水膜替代無水鈉隔離雜質(zhì)和水分，分離出油和化碳的溶液，測定總萃取物含油量。它是一種新型的精細(xì)檢測設(shè)備，在實驗室內(nèi)也較為常見。動輒幾萬元的價錢考驗著操作人員的仔細(xì)水平。因而，學(xué)習(xí)相關(guān)操作知識是十分有必要的。一定要將失誤遏止在萌芽階段。下面是一些操作留意事項，希望對大家有所協(xié)助。</p><p>　　1、所用應(yīng)為剖析純以上并經(jīng)活性炭過濾提純或蒸餾提純，經(jīng)儀器驗證合格前方可運用，考證辦法可參考本闡明書相關(guān)局部。</p><p>　　2、照明的光學(xué)器件應(yīng)防止人手觸摸，盡量防止灰塵的沾污。若光學(xué)鏡面沾有手印或灰塵，能夠在技術(shù)人員指導(dǎo)下用*或丙酮沖洗鏡面，關(guān)于光柵不能這樣清洗，需專業(yè)人員才干維護。</p><p>　　3、初次運用時應(yīng)預(yù)熱30分鐘后再停止丈量。</p><p>　　4、假如在初次操作過程中發(fā)現(xiàn)異常現(xiàn)象，應(yīng)立刻關(guān)閉主機電源和微機，然后重新開機工作。</p><p>　　5、測油文件保管在c盤目錄下，經(jīng)常在其它盤上對結(jié)果的文件夾備份。</p><p>　　6、操作紅外測油儀的時分應(yīng)帶實驗用手套，打開通風(fēng)設(shè)備，堅持空氣流通，避免四氯化碳揮發(fā)對人體形成損傷。</p><p
