class="title">詳細(xì)說(shuō)明</p><div id="rn9jxtj" class="box"><p><p> 分光光度計(jì)作為一種精密儀器，在運(yùn)行工作過(guò)程中由于工作環(huán)境、操作方法等種種原因，其技術(shù)狀況必然會(huì)發(fā)生某些變化，可能影響設(shè)備的性能，甚至誘發(fā)設(shè)備故障及事故。因此，分析工作者必須了解分光光度計(jì)的基本原理和使用說(shuō)明，并能及時(shí)發(fā)現(xiàn)和排除這些隱患，對(duì)已產(chǎn)生的故障及時(shí)維修才能保證儀器設(shè)備的正常運(yùn)行。 </p> <p> 紫外可見分光光度計(jì)--使用經(jīng)驗(yàn) </p> <p> 若大幅度改變測(cè)試波長(zhǎng)，需稍等片刻，等燈熱平衡后，雙光束紫外可見分光光度計(jì)選擇，重新校正“0”和“100%”然后再測(cè)量。 </p> <p> 指針式儀器在未接通電源時(shí)，電表的指針必須位于零刻度上。若不是這種情況，需進(jìn)行機(jī)械調(diào)零。 </p> <p> 比色皿使用完畢后，請(qǐng)立即用蒸餾水沖洗干凈，并用干凈柔軟的紗布將水跡擦去，以防止表面光潔度被破壞，影響比色皿的透光率。 </p> <p> 操作人員不應(yīng)輕易動(dòng)燈泡及反光鏡燈，以免影響光效率。 </p> <p> 1900型等分光光度計(jì)，由于其光電接收裝置為光電倍增管，它本身的特點(diǎn)是放大倍數(shù)大，因而可以用于檢測(cè)微弱光電信號(hào)，而不能用來(lái)檢測(cè)強(qiáng)光。否則容易產(chǎn)生信號(hào)漂移，雙光束紫外可見分光光度計(jì)選擇，靈敏度下降。 </p> <p> 針對(duì)其上述特點(diǎn)，在維修、使用此類儀器時(shí)應(yīng)注意不讓光電倍增管長(zhǎng)時(shí)間暴露于光下，因此在預(yù)熱時(shí)，應(yīng)打開比色皿蓋或使用擋光桿，雙光束紫外可見分光光度計(jì)選擇，避免長(zhǎng)時(shí)間照射使其性能漂移而導(dǎo)致工作不穩(wěn)。測(cè)量吸光度并不是測(cè)量透過(guò)吸收池的光強(qiáng)度，而是將光強(qiáng)度轉(zhuǎn)換成電流進(jìn)行測(cè)量，稱為紫外分光光度計(jì)的檢測(cè)器。雙光束紫外可見分光光度計(jì)選擇</p><div

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(guò)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(guò)大或過(guò)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。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。 </p> <p> 可通過(guò)控制被測(cè)物濃度或改變吸收池厚度來(lái)實(shí)現(xiàn)吸光度合理的范圍，以盡量減小測(cè)量誤差。一般吸光度盡量控制在0.1-0.8范圍。 </p> <p> 空白溶液是用來(lái)調(diào)節(jié)吸光度測(cè)量工作零點(diǎn)即A=0，T=100%的溶液，以消除溶液中其它基體組分以及吸收池和溶劑對(duì)入射光的反射和吸收所帶來(lái)的誤差。根據(jù)情況不同，常用空白溶液有如下幾種選擇。 </p> <p> <br /> 甲醇紫外可見分光光度計(jì)代理通常我們所理解的單色光，只是存于理想狀態(tài)下，實(shí)際上得到的“單色光”，是帶有一定寬度和波長(zhǎng)范圍的譜帶。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

紫外可見分光光度計(jì)的軟件功能可以極大地提升儀器的使用性能和價(jià)值，現(xiàn)代分光光度計(jì)生產(chǎn)廠商都非常重視儀器配套軟件的開發(fā)。除了儀器控制軟件和通用數(shù)據(jù)分析處理軟件外，很多儀器針對(duì)不同行業(yè)應(yīng)用開發(fā)了**分析軟件，給儀器使用者帶來(lái)了極大的便利。 </p> <p> 紫外可見分光光度計(jì)的結(jié)構(gòu)一般地，紫外可見分光光度計(jì)主要由光源系統(tǒng)、單色器系統(tǒng)、樣品室、檢測(cè)系統(tǒng)組成，如圖1所示。光源發(fā)出的復(fù)合光通過(guò)單色器被分解成單色光，當(dāng)單色光通過(guò)樣品室時(shí)，一部分被樣品吸收，其余未被吸收的光到達(dá)檢測(cè)器，被轉(zhuǎn)變?yōu)殡娦盘?hào)，經(jīng)電子電路的放大和數(shù)據(jù)處理后，通過(guò)顯示系統(tǒng)給出測(cè)量結(jié)果。 </p><p> 雜散光：典型值是0.01～0.05%T，在國(guó)外的產(chǎn)品中有65種產(chǎn)品的雜散光指標(biāo)在這一范圍中。雜散光超過(guò)0.05%T的產(chǎn)品有31種，小于0.01%T的產(chǎn)品有19種。。從其光學(xué)設(shè)計(jì)看，都采用了雙單色器。與掃描光柵型產(chǎn)品相比，固定光柵的分光光度計(jì)少了出射狹縫，實(shí)現(xiàn)低雜散光的難度更大。從性能指標(biāo)來(lái)看，范圍是0.01～1%T。26種固定光柵型產(chǎn)品中雜散光在0.01～0.05%T之間的有13種，也已達(dá)到半數(shù)，但是能夠低于0.01%T的很少。波長(zhǎng)準(zhǔn)確性，國(guó)外的典型水平是0.1～1nm。國(guó)內(nèi)產(chǎn)品中，處于此范圍的有16種，基本達(dá)到同一水平，但沒有優(yōu)于0.1nm的產(chǎn)品。國(guó)內(nèi)產(chǎn)品的光度準(zhǔn)確性大多以透過(guò)率表示，水平比較接近，均在0.3～0.5%T之間。在10%T處，也就是吸光度為1A處，將光度準(zhǔn)確性以吸光度表示，則數(shù)值為0.013～0.021A。與國(guó)外產(chǎn)品有比較明顯的差距。國(guó)內(nèi)產(chǎn)品的光度重復(fù)性基本在0.1～0.3%T范圍，同樣在吸光度1A處換算，數(shù)值為0.004～0.013A，也存在距離。比較國(guó)外與國(guó)內(nèi)產(chǎn)品的雜散光的典型值，兩者幾乎相差了一個(gè)數(shù)量級(jí)。但是已有一些較新研發(fā)的產(chǎn)品，可以達(dá)到國(guó)外產(chǎn)品的普遍水準(zhǔn)。紫外可見分光光度計(jì)基本工作原理和紅外光譜儀相似，利用一定頻率的紫外可見光照射被分析的有機(jī)物質(zhì)。</p><div

掌握紫外可見光分光光度計(jì)基本工作原理：一定頻率紫外可見光照射所需要分析的目標(biāo)樣品，引起目標(biāo)樣品中價(jià)電子發(fā)生躍遷，從而變現(xiàn)隨著吸收波長(zhǎng)變化而引起光譜變化，形成可供分析數(shù)據(jù)。 </p> <p> 以朗伯-比耳定律(Lambert-beer)為理論基礎(chǔ)，特定波長(zhǎng)吸收中，吸收程度正比于試樣成分濃度，因此，可進(jìn)行光譜的定性分析。且根據(jù)吸收與已知濃度標(biāo)樣比較，能進(jìn)行定量分析。 </p> <p>
