在定量分析中，為了提高測(cè)定的靈敏度，入射光的波長(zhǎng)應(yīng)選擇被測(cè)物的MAX吸收波長(zhǎng)λmax，如果λmax有干擾，可選擇另一條靈敏度稍低、但能避免干擾的譜線，所以，適當(dāng)選擇入射光的波長(zhǎng)，不僅能提高測(cè)定的靈敏度，還能提高測(cè)定的準(zhǔn)確度。 </p> <p> 狹縫寬度過大，入射光的單色性差；狹縫寬度太小，入射光的強(qiáng)減弱。狹縫寬度過大或過小均會(huì)造成靈敏度降低，選擇是產(chǎn)生MIN誤差情下的MAX狹縫，化工紫外可見分光光度計(jì)現(xiàn)貨。一般選用儀器的狹縫寬琶度應(yīng)小于待測(cè)樣品吸收帶的半寬度，否則測(cè)得的吸光度值會(huì)偏低，狹縫寬度的選擇應(yīng)以減少狹縫寬度時(shí)供試品的吸光度不再；加為準(zhǔn)，對(duì)于大部分被測(cè)品種，可以使用2nm縫寬。

對(duì)于紫外可見分光光度計(jì)，由于有雙光源(鎢燈與氘燈)，為了延長(zhǎng)燈的使用壽命，開機(jī)自檢完成后可以關(guān)掉測(cè)定時(shí)不用的光源燈。紫外可見分光光度計(jì)使用中常見問題解析在一般分光光度計(jì)的使用說明書上，要求儀器預(yù)熱時(shí)間約20分鐘；若是帶微處理器的分光光度計(jì)，開機(jī)后儀器自動(dòng)進(jìn)入自檢(初始化)狀態(tài)，約需1O分鐘左右。在分光光度計(jì)預(yù)熱這個(gè)環(huán)節(jié)上，很多使用者或多或少存在問題，如開機(jī)只預(yù)熱電路系統(tǒng)(不調(diào)節(jié)波長(zhǎng)、打開吸收池暗箱蓋預(yù)熱等)或認(rèn)為初始化過程就是預(yù)熱等等。對(duì)帶微處理器有自檢功能的分光光度計(jì)，開機(jī)后儀器自檢(初始化)結(jié)束后，在測(cè)定窗口上，設(shè)置所需波長(zhǎng)值，用一個(gè)吸收池裝上純凈水置于光路上，調(diào)“0000A”后，預(yù)熱儀器，當(dāng)儀器顯示讀數(shù)不再變化后即可進(jìn)行測(cè)定。 </p> <p> <br /> </p><p> 紫外可見分光光度計(jì)的基本結(jié)構(gòu)紫外可見分光光度計(jì)的工作原理是由光源發(fā)出連續(xù)輻射光，經(jīng)單色器按波長(zhǎng)大小色散為單色光，單色光照射到吸收池，一部分被樣品溶液吸收，未被吸收的光經(jīng)檢測(cè)器的光電管將光強(qiáng)度變化轉(zhuǎn)變?yōu)殡娦盘?hào)變化，并經(jīng)信號(hào)顯示系統(tǒng)調(diào)制放大后，顯示或打印出吸光度A（或透射比T），完成測(cè)定。 </p> <p> 鎢燈是常用的可見光光源，它可發(fā)射的波長(zhǎng)為325~2500nm的連續(xù)光譜，其中適宜的使用波長(zhǎng)范圍為320~1000nm，因此，也可用做近紅外光源。電能將鎢燈加熱到白熾時(shí)，發(fā)出的光強(qiáng)度在各波段的分布隨燈絲溫度而變化。燈絲的溫度取決于電源電壓。電源電壓的微小波動(dòng)都會(huì)引起鎢光強(qiáng)度的很大變化。因此必須使用穩(wěn)壓電源供電，鎢燈工作電壓為12V，也可以使用12V的直流電源供電。鎢燈的壽命一般可達(dá)10000小時(shí)以上。 </p> <p> 目前很多光度計(jì)采用鹵鎢燈代替鎢燈，如7230G型、752PLUS型分光光度計(jì)等。鹵鎢燈具有較高的發(fā)光效率和較長(zhǎng)的使用壽命。紫外可見光分光光度計(jì)是使用紫外光譜特點(diǎn)而設(shè)計(jì)制造的光學(xué)儀器。</p><div style="width:100%;text-align: center;"><img

色譜技術(shù)比它起步晚了二百多年，但如今的色譜儀器（氣相、液相、氣質(zhì)、液質(zhì)）占了分析界的大半壁江山。相較璀璨如星的各類的色譜儀器，紫外-可見分光光度計(jì)黯然了很多。 </p> <p>
