style="text-indent:25px">原子吸收分光光度計的開展：1981年原子吸收分光光度計完成操作自動化。1984年首臺連續(xù)氫化物發(fā)生器面世。1990年推出世界上先進的MarkV1焰燃燒頭。1995年在線火焰自動進樣器（SIPS8）研制成功并投入運用。1998年首臺快速剖析火焰原子吸收220FS誕生。2002年世界上**火焰和石墨爐同時剖析的原子吸收光譜儀出產(chǎn)并投放市場。原子吸收分光光度計怎樣用才正確？該崗位群主要是散布于冶金、環(huán)保、食物、制藥、醫(yī)療衛(wèi)生、化學、化工、農(nóng)業(yè)等領域，主要從事環(huán)境和產(chǎn)品中金屬物質(zhì)的檢驗以及科學研制的質(zhì)量操控等工作。</p><p style="text-indent:25px">原子吸收分光光度計詳細組成部分如下：組成部分一：電光體系。在該體系中首要是由鎢燈和相應的電源組成，這種體系對整體的穩(wěn)定性就有很大影響，當該體系不能正常工作后也會導致儀器工作不穩(wěn)定。組成部分二：光學體系。這種體系包含有外光路體系和單色器2個首要部分，其間外光路和單色器都有很多類型，單色器便是紫外可見分光光度計散光的首要來歷。組成部分三：光電體系。該體系是紫外可見分光光度計要害的部件，體系會直接影響到儀器中的靈敏度和適用范圍，里邊有光電倍增管、光電管和硅光電池等。火焰原子吸收分光光度計對大多數(shù)元素有較高靈敏度。</p><div

style="text-indent:25px">原子吸收分光光度計存在理化方面的干擾。上海**原子吸收分光光度計設備</p><p style="text-indent:25px">哪些是原子吸收分光光度計的特點?原子吸收分光光度計(AAS)簡稱原子吸收法，是使用被測元素基態(tài)原子蒸氣對其共振輻射線的吸收特性進行元素定量剖析的方法。原子吸收分光光度計具有以下特色：①靈敏度高：慣例剖析法對大多數(shù)元素可到達ppm級;使用特別手法可到達ppb級的濃度范圍;②精密度好：一般測定RSD約為1%～3%，使用特別方法精密度可小于1%。③使用范圍廣：周期表中70多種元素可使用該法測定：④干擾少：原子吸收光譜為分立的銳線光譜，且譜線堆疊性少，干擾性小;⑤試樣用量少：選用石墨爐無火焰原子吸收法，每次丈量*需5～20μl試液或0.05～10mg的固體試樣;⑥快速簡潔，易于自動化：液體試樣?？芍苯舆M樣，一般樣品無需進行預別離處理，新型號產(chǎn)品儀器的進樣和測定步驟全部自動化完成。上海**原子吸收分光光度計設備</p></p><br
