為了測(cè)量吸光值，分光光度計(jì)制造商通常使用光電倍增管（photo-multipliertubes，PMTs）和光敏二極管。PMTs提供快速的反應(yīng)時(shí)間和良好的靈敏度，并且可以在紫外光譜調(diào)節(jié)至特定的范圍。但一些制造商依賴于光敏二極管的動(dòng)態(tài)范圍在數(shù)秒內(nèi)行使所有的光譜測(cè)量。

可見分光光度計(jì)常見的有721系列，722系列和723系列。721系列可見分光光度計(jì)有721/721-100型，測(cè)定波長為360-800nm，分為分指針和數(shù)顯式兩種方式的顯示器。其中721-100型相對(duì)于721是型將測(cè)試樣品室加寬，可用10cm的比色皿，為糖廠**檢測(cè)儀器。722系列可見分光光度計(jì)有722/722S/722N型，測(cè)定波長為330-1000nm/325-1000nm。722型波長是330-1000nm，722S與722N的波長范圍325-1000nm，其中722N是自動(dòng)調(diào)節(jié)波長。723系列可見分光光度計(jì)有723/723N/723PC/723PCS型四種，測(cè)定波長為320-1000nm，其中723是手動(dòng)調(diào)整波長，723N是自動(dòng)調(diào)波長，723PC配有掃描軟件，723PCS帶有掃描軟件和打印機(jī)。紫外可見分光光度計(jì)常見的是UV752/UV752N，波長范圍是195nm-1020nm。二者<span style="display:none;"></span>主要區(qū)別是UV752N可以選配打印機(jī)將數(shù)據(jù)輸出，其中在雜散光參數(shù)，光譜帶寬等方面還有細(xì)微的差別。紫外可見光的范圍內(nèi)，對(duì)于一個(gè)特定的波長，吸收的程度正比于試樣中該成分的濃度，可以進(jìn)行定性分析。中國**紫外可見分光光度計(jì)設(shè)備</p><p style="text-indent:25px">分光光度分析就是根據(jù)物質(zhì)的吸收光譜研究物質(zhì)的成分、結(jié)構(gòu)和物質(zhì)間相互作用的有效手段。國內(nèi)**紫外可見分光光度計(jì)選擇</p><p> <br /> </p> <p> 自從60年前紫外分光光度計(jì)出現(xiàn)在實(shí)驗(yàn)室的工作臺(tái)之后，已經(jīng)形成了一種能解決大部分難題的儀器，從單一波長的測(cè)量到高性能多光譜的測(cè)量分析。實(shí)驗(yàn)室選擇時(shí)需要根據(jù)自己實(shí)驗(yàn)室的需要和目的用途來考慮，光學(xué)構(gòu)造和光源、探測(cè)方法、樣品類型和數(shù)據(jù)處理等都是要考慮的因素。 </p> <p> <br /> </p> <p> 光學(xué)構(gòu)造（OPTICALCONFIGURATION） </p> <p> <br /> </p> <p> 一般來說，紫外光分光光度計(jì)分為單光束和雙光束兩類。顧名思義，單光束型主要是依賴單束光進(jìn)行測(cè)量。一束給定波長的光通過對(duì)照物，然后再通過實(shí)際樣品溶液，就能得到吸光結(jié)果。 </p> <p> <br /> </p> <p> <br /> </p> <p> 雙光束型則是通過一個(gè)斬光輪（mirroredchopperwheel）將一束光分成兩束，分別測(cè)量對(duì)照樣品和實(shí)際樣品?？梢訫IN光漂移（lampdrift）和減少測(cè)量時(shí)間。一些雙光型光度計(jì)不利用斬光輪，而是利用一種光束分光器來代替，將一束光分成兩束平行的光然后同時(shí)測(cè)量對(duì)照樣品和目的樣品。因?yàn)樵黾恿藴y(cè)量的速度，所以雙光束分光光度計(jì)在測(cè)量一些溶液隨時(shí)間動(dòng)態(tài)變化的研究中大有用處。
