氧氮?dú)浞治鰞x的使用注意事項(xiàng)：1、氧氮?dú)浞治鰞x在初次啟用前，應(yīng)該對(duì)連接點(diǎn)、焊點(diǎn)、閥門等進(jìn)行檢漏，以確保空氣中的氧不會(huì)反滲進(jìn)入管道及儀器內(nèi)部，造成測(cè)量數(shù)值偏高。2、再次使用儀器前，要進(jìn)行管道系統(tǒng)凈化，將漏入的空氣除干凈，同時(shí)確保連接取樣管路時(shí)沒(méi)有漏入空氣。3、樣氣中氧含量的變化會(huì)受管道材質(zhì)及表面粗糙度影響，因此一般連接管路選用銅管或拋光過(guò)的不銹鋼管，而不用塑料管、橡膠管等。4、微量元素分析時(shí)，要避免各種管件、閥門、表頭等死角對(duì)樣氣造成污染，因此必須盡可能的簡(jiǎn)化氣路系統(tǒng)，連接件死角要小，以防止溶解氧逸出造成污染，使用水封、油封及臘封等設(shè)備，才能較好的確保數(shù)據(jù)的。上海禹重實(shí)業(yè)有限公司致力于提供分析儀，竭誠(chéng)為您服務(wù)。江蘇美國(guó)LECO分析儀采購(gòu)
