style="text-indent:25px">原子吸收光譜儀分析中的干擾效應(yīng)：1、電離干擾：在高溫下原子電離，使基態(tài)原子的濃度減少，引起原子吸收信號降低，此種干擾稱為電離干擾。電離效應(yīng)隨溫度升高、電離平衡常數(shù)增大而增大，隨被測元素濃度增高而減小。加入更易電離的堿金屬元素，可以有效地消除電離干擾。2、光譜干擾：光譜干擾包括譜線重疊、光譜通帶內(nèi)存在非吸收線、原子化池內(nèi)的直流發(fā)射、分子吸收、光散射等。當(dāng)采用銳線光源和交流調(diào)制技術(shù)時，主要考慮分子吸收和光散射的影響，它們是形成光譜背景的主要因素。儀器出廠前需經(jīng)質(zhì)檢部門按專業(yè)規(guī)范或企業(yè)規(guī)范檢定。低端原子吸收分光光度計經(jīng)銷商</p><p
