id="wowgyyywegmg" class="NyNewsdetail_tips">更新時間：2023-05-25 點擊次數(shù)：841</div> <div id="wowgyyywegmg" class="NyNewsdetail_con"> <div><span style="font-size: 16px;">　　COD快速測定儀是一種使用電子技術、光學技術和化學分析方法結合的設備，能夠快速、準確地測定水樣中的化學需氧量。下面將介紹它的使用方法。</span></div><div><span style="font-size: 16px;"><br /></span></div><p align="center"><img src="https://img63.chem17.com/9/20230525/638206333669656196546.jpg" width="560" height="397" align="middle" alt="" /></p><p> </p><div><span style="font-size: 16px;">　　COD快速測定儀的使用方法：</span></div><div><span style="font-size: 16px;">　　第一步：樣品處理</span></div><div><span style="font-size: 16px;">　　將需要測試的水樣取一定量，通常為10毫升，然后加入COD試劑，通常為硫酸鉀二鉻酸鉀溶液。注意要避免與試劑接觸產(chǎn)生劇烈反應，并保持樣品表面平整。樣品中還可以添加催化劑（比如銀催化劑），以加速COD反應的進行。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　第二步：裝載樣品</span></div><div><span style="font-size: 16px;">　　將處理好的樣品倒入儀器的測量池中，注意不要超過標尺線。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　第三步：設定參數(shù)</span></div><div><span style="font-size: 16px;">　　按照儀器說明書設置儀器所需的參數(shù)，包括反應時間、溫度等。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　第四步：啟動儀器</span></div><div><span style="font-size: 16px;">　　啟動儀器，開始測量。在測量過程中，儀器會自動記錄測量數(shù)據(jù)。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　第五步：讀取結果</span></div><div><span style="font-size: 16px;">　　待測量完成后，從儀器上讀取測量結果。COD快速測定儀通常會顯示出化學需氧量的數(shù)值。如果需要，還可以將數(shù)據(jù)通過儀器上的接口導出至電腦等其他設備進行進一步分析。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　第六步：維護設備</span></div><div><span style="font-size: 16px;">　　使用完后，要及時清洗、干燥和保養(yǎng)設備，以確保下次使用時正常運作。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　需要注意的是，在操作時，要遵循嚴格的安全規(guī)范，防止試劑濺出或誤操作造成危險。此外，為了獲得更準確的測量結果，還需要注意樣品處理和儀器設定的精度和標準化程度。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;">　　總之，COD快速測定儀是一種非常實用的水質(zhì)檢測設備，能夠幫助我們快速、準確地了解水體中化學需氧量的情況。通過以上介紹的使用方法，相信大家已經(jīng)對該設備的操作有了一定的了解。</span></div> </div> <div id="wowgyyywegmg" class="ly_PrevNext"> <ul>
