style="text-indent:25px">原子吸收分光光度計組成：利用待測元素的共振輻射，通過其原子蒸汽，測定其吸光度的裝置稱為原子吸收分光光度計。它有單光束，雙光束，雙波道，多波道等結(jié)構(gòu)方式。其根本結(jié)構(gòu)包含光源，原子化器，光學(xué)體系和檢測體系。原子吸收分光光度計首要用于痕量元素雜質(zhì)的分析，具有靈敏度高及選擇性好兩大首要長處。多應(yīng)用于特種氣體，金屬有機化合物，金屬醇鹽中微量元素的分析?？墒菧y定每種元素均需求相應(yīng)的空心陰燈，這對檢測工作帶來不便。</p><p style="text-indent:25px">原子吸收分光光度計在日常作業(yè)中應(yīng)經(jīng)常檢查乙炔鋼瓶與減壓閥連接是否結(jié)實無漏氣。留意燃燒、關(guān)火次序。燃燒后操作人員不得離開！在當(dāng)天不必儀器操作時,請將乙炔管道里的剩下氣體燃燒完，即直接關(guān)乙炔總開關(guān)再管空氣。帶石墨爐的儀器必定要留意用電安全,因為會運用380V動力電，加熱時瞬間會發(fā)生很大的電流,所以在石墨爐處于作業(yè)狀況時，不要直接觸碰爐體部分，避免造成風(fēng)險.在做試驗時隨時調(diào)查氬氣的總壓力和內(nèi)氣流量計的流量,以確保石墨管可以長期運用和試驗的準確和一致性。原子吸收分光光度計一般靈敏度在ng/ml級（10-9），相對標(biāo)準偏差2%左右。</p><div

style="text-indent:25px">原子吸收分光光度計的兩大特色：1.選擇性強。因為原子吸收分光光度計譜線*發(fā)生在主線系，并且譜線很窄，線重疊幾率較發(fā)射光譜要小得多，所以光譜攪擾較小選擇性強，并且光譜攪擾簡單戰(zhàn)勝。在大多數(shù)情況下，共存元素不對原子吸收分光光度計剖析發(fā)生攪擾。因為選擇性強，使得剖析精細快速。即每種待測元素都要有一個能發(fā)射特定波長譜線的光源。原子吸收分光光度計剖析中，首要要使待測元素呈原子狀態(tài)，而原子化往往是將溶液噴霧到火焰中去實現(xiàn)，這就存在理化方面的攪擾，使對難溶元素的測定靈敏度還不夠抱負，因此實際效果抱負的元素*30余個；因為儀器運用中，需用乙炔、氫氣、氬氣、氧化亞氮等，操作中需要注意。原子吸收分光光度計對空心陰極燈發(fā)射的特征輻射進行選擇性吸收。材料原子吸收分光光度計排名</p><p
