style="text-indent:25px">原子吸收光譜分析工作原理：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)形式。其基本結(jié)構(gòu)包括光源，原子化器，光學(xué)系統(tǒng)和檢測系統(tǒng)。它主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主要優(yōu)點。多應(yīng)用于各種氣體，金屬有機化合物，金屬醇鹽中微量元素的分析。但是測定每種元素均需要相應(yīng)的空心陰極燈，這對檢測工作帶來不便。火焰原子化法的優(yōu)點是：火焰原子化法的操作簡便，重現(xiàn)性好，有效光程大，對大多數(shù)元素有較高靈敏度，因此應(yīng)用多。缺點是：原子化效率低，靈敏度不夠高，而且一般不能直接分析固體樣品。我國在1963年開始對原子吸收分光光度計有一般性介紹。學(xué)校原子吸收分光光度計生產(chǎn)廠家</p><p

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?？煽吭游辗止夤舛扔嫸嗌馘X</p><p
