style="text-indent:25px"> 標準氣體的特殊性，對采樣有著特殊的要求，很多使用者由于采樣的不規(guī)范，使得數(shù)據(jù)偏差很大，在這里我提供樣品取樣應該注意的幾個方面：1、取樣管線的選擇，由于膠管使用起來很方便，很多傳統(tǒng)的進樣管線都采用此類，但是眾所周知，膠管對大部分有機氣體，和含硫類的氣體吸附性非常強，而且它的滲透性也很強，所以使用各類膠管來采樣是不可取的，對分析數(shù)據(jù)造成很大偏差。建議根據(jù)不同的氣體性質(zhì)采用銅管、不銹鋼管、四氟管而對于含硫的標準氣和樣品氣比較好采用內(nèi)涂石英的不銹鋼管。2、樣品氣的置換，由于標準氣都要經(jīng)過減壓器和管線后才能取樣，要準確取樣必須將減壓器和管線進行充分的置換，這種置換不是簡單意義上的吹掃。因為減壓器的死體積很大，不斷將鋼瓶閥打開關(guān)閉反復3次以上，每次將減壓器里的氣體排盡，然后再吹掃系統(tǒng)才能正確取樣。3、進樣管線的氣密性，進樣管線的泄漏，對樣品的數(shù)據(jù)的準確性有很大影響，對低濃度氧氣的影響更大。所以一定要嚴格檢查取樣管線的氣密性。4、試圖從標準氣體鋼瓶中把標準氣取到取樣袋或其他容器中，然后再從容器中取樣分析，是非常不可取的，這樣造成了二次污染。使得樣品氣的數(shù)據(jù)不能真實的表現(xiàn)出來。</p><p style="text-indent:25px"> 工業(yè)氣體的常見物理特性，可歸納為：可壓縮性和膨脹性。一定量的氣體在溫度基本保持不變時，所加的壓力越大其體積就會變得越小，若繼續(xù)加壓，氣體將會壓縮成液體，這就是氣體的可壓縮性。工業(yè)氣體通常以壓縮或液化狀態(tài)儲存于鋼瓶內(nèi)。氣體在光照或受熱后，溫度升子間的熱運動加劇，體積增大，若在一定容器內(nèi)，氣體受熱的溫度越高，其膨脹后形成的壓力越大，這就是氣體受熱的膨脹性。壓縮氣體和液化氣體盛裝在容器內(nèi)，如受高溫、日曬，氣體極易膨脹，產(chǎn)生很大的壓力，當壓力超過容器的耐壓強度，就會造成。因此，工業(yè)氣體均具有極大的危險性。氣體，就選常州大成工業(yè)氣體有限公司，用戶的信賴之選，歡迎您的來電哦！</p><div

style="text-indent:25px"> 在基于紅外光譜技術(shù)的混合氣體檢測中，光學復用結(jié)構(gòu)是檢測系統(tǒng)的中心部分，它既是紅外光傳播的媒介，又是氣體吸收紅外光能的主要場所。根據(jù)光能變換過程的差別，可以將紅外光譜檢測技術(shù)分為兩種：直接檢測和間接檢測。NDIR光譜技術(shù)中采用寬帶光源，通過選擇不同中心波長和帶寬的濾光元件得到與氣體吸收特性匹配的近似單色光，然后直接被探測器探測。探測器通常集成了濾光元件，包括作用通道和參考通道，作用通道輸出的信號分別與參考信號進行一定的運算，以消除光源、探測器不穩(wěn)定以及外界干擾等因素帶來的影響。光源的選擇與控制、濾光元件參數(shù)的選取以及光源與探測器的匹配程度等問題，在NDIR光譜技術(shù)中都是值得深入研究的。Danilova等在實驗中已經(jīng)證明，適當降低驅(qū)動電流脈沖占空比可以提高光源發(fā)光效率。而合理選取濾光元件，有利于確定氣體吸收的比較好參數(shù)。為了避免紅外熱光源在調(diào)制頻率較低（小于10Hz）的情況下帶來的1/f噪聲，選取高調(diào)制頻率的LED光源和具有低時間常數(shù)的探測器，可以提高整個系統(tǒng)的檢測速度，降低噪聲。常州大成工業(yè)氣體有限公司為您提供氣體，歡迎新老客戶來電！蕪湖FM200氣體價格</p><p

為了保證所制備的標準氣體量值的準確性和可比性，應經(jīng)常進行量值比對。比對的形式有方法比對、實驗室之間的比對、國際比對等。方法比對，非常常見的是用重量法制備的標準氣體。為了防止稱量時的流失，通常采用氣相色譜法進行分析比對，以保證制備的標準氣體的不確定度在合理的范圍內(nèi)。一般說來，重量法制備標準氣體的不確定度優(yōu)于1%，如果用氣相色譜法分析，比對結(jié)果偏差優(yōu)于2%，應逐級查找原因，以保證量值的準確性。實驗室之間的比對、國際比對應由牽頭實驗室與二、三個提名比對實驗室與二、三個提名比對實驗室擬定詳細的比對技術(shù)方案。比對的技術(shù)方案應包括：1、樣品的詳細描述；2、運輸過程的注意事項；3、比對實驗室在接收樣品時應采取的措施；4、比對開始前應進行的檢驗，如壓力等；5、比對分析時使用標準的條件；6、比對結(jié)果的說明；7、如何估處不確定度；8、參加比對的每個標準對SI單的溯源性；9、比對結(jié)果與牽頭實驗室溝通的時間表；10、比對經(jīng)費；11、比對結(jié)果的報告格式。駐馬店混合氣體滅火</p><p
