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(xì)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(fù)，因此實際效果抱負(fù)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。常用原子吸收分光光度計排名原子吸收分光光度計采用新的電子技術(shù)。</p><div

style="text-indent:25px">通常情況下，原子處于基態(tài)。當(dāng)相當(dāng)于原子中的電子由基態(tài)躍遷到激發(fā)態(tài)所需求的輻射頻率經(jīng)過原子蒸氣，原子就能從入射輻射中吸收能量，發(fā)生共振吸收，然后發(fā)生吸收光譜。原子吸收剖析便是使用基態(tài)原子對特征輻射的吸收程度的，常使用強吸收線作為剖析線。原子吸收光譜儀由以下四部分組成光源系統(tǒng):空心陰燈原子化系統(tǒng):火焰原子化器;原子吸收分光光度計或氫化物發(fā)生器。分光系統(tǒng)：單色器檢測系統(tǒng)：光電倍增管等。原子吸收分光光度計的長處是:原子化效率高，在可調(diào)的高溫下試樣使用率達(dá)100，活絡(luò)度高，試樣用量少，適用于難熔元素的測定。缺陷是:試樣組成不均勻性的影響較大，測定度較低，共存化合物的攪擾比火焰原子化法大，攪擾布景比較嚴(yán)重，一般都需求校正布景。</p><p
