使用紫外分光光度計(jì)的過程中，經(jīng)常會(huì)遇到儀器因光源達(dá)不到要求，需要進(jìn)行調(diào)修。要求光源燈處不能有空氣流動(dòng)，因?yàn)閱喂馐鴥x器很忌諱空氣快速流動(dòng)而使光源燈的色溫發(fā)生變化。如遇電壓正常而鎢燈不亮?xí)r，就需要更換鎢燈。更換時(shí)，不要用手直接接觸燈泡表面，如果手指摸過，應(yīng)用無水乙醇和C4H10O混合液擦拭干凈，否則通電后指印遇熱不能去除。安裝光源燈后要注意調(diào)整光路。光源燈有兩個(gè)引線頭，安裝時(shí)用導(dǎo)線焊接，主要是防止接觸不良而造成的光源發(fā)光不穩(wěn)現(xiàn)象。在焊接時(shí)防止焊點(diǎn)與燈頭銅皮碰上，裝上燈座使電源短路。燈絲要求平直，如果燈絲彎曲，會(huì)影響光能量。燈絲的位置要與入射狹縫平行并對(duì)準(zhǔn)，上，環(huán)境檢測(cè)紫外可見分光光度計(jì)單價(jià)、下、左、右調(diào)節(jié)后緊固螺釘。擰緊燈座的螺紋套，環(huán)境檢測(cè)紫外可見分光光度計(jì)單價(jià)，可用鉗子擰緊，一般燈頭盡量往燈座里塞，環(huán)境檢測(cè)紫外可見分光光度計(jì)單價(jià)，因?yàn)槎鄶?shù)燈絲離燈頭偏高。調(diào)整燈位置的前后可移動(dòng)整個(gè)燈座架，它下面有三個(gè)固定螺釘，先稍松后，移動(dòng)前后位置再固定。一般調(diào)節(jié)鎢燈的位置時(shí)，將波長(zhǎng)調(diào)到580nm處，狹縫調(diào)到MAX，把一張白紙置于比色皿盒邊出口處，觀察白紙上的光斑。若光斑上方左右角均不完整成半圓弧，可能是光源燈高度不對(duì)；光斑左邊或右邊不完整，可調(diào)光源燈底座位置。調(diào)整至白紙上可見明亮、均勻的長(zhǎng)方形黃橙色光斑。傳統(tǒng)單光束UV紫外測(cè)試，測(cè)試過程全程封閉，單光束光源只通過光柵直接照射樣品，再經(jīng)光電倍增管檢測(cè)器檢測(cè)。環(huán)境檢測(cè)紫外可見分光光度計(jì)單價(jià)</p><div

什么是紫外可見分光光度計(jì)？紫外可見分光光度計(jì)是一類很重要的分析儀器，無論在物理學(xué)、化學(xué)、生物學(xué)、醫(yī)學(xué)、材料學(xué)、環(huán)境科學(xué)等科學(xué)研究領(lǐng)域，還是在化工、醫(yī)藥、環(huán)境檢測(cè)、冶金等現(xiàn)代化生產(chǎn)與管理部門，紫外可見分光光度計(jì)都有重要的應(yīng)用。 </p> <p> 分光光度計(jì)是杜包斯克(Duboscq)和奈斯勒(Nessler)等人在1854年將朗伯-比爾(Lambert-Beer)定律應(yīng)用于定量分析化學(xué)領(lǐng)域，并且設(shè)計(jì)了第1臺(tái)比色計(jì)。到1918年，美國國家標(biāo)準(zhǔn)局制成了第1臺(tái)紫外可見分光光度計(jì)。此后，紫外可見分光光度計(jì)經(jīng)不斷改進(jìn)，又出現(xiàn)自動(dòng)記錄、自動(dòng)打印、數(shù)字顯示、微機(jī)控制等各種類型的儀器，使光度法的靈敏度和準(zhǔn)確度也不斷提高，其應(yīng)用范圍也不斷擴(kuò)大。紫外可見分光光度法從問世以來，在應(yīng)用方面有了很大的發(fā)展，尤其是在相關(guān)學(xué)科發(fā)展的基礎(chǔ)上，促使分光光度計(jì)儀器的不斷創(chuàng)新，功能更加齊全，使得光度法的應(yīng)用更拓寬了范圍。目前，分光光度法已為工農(nóng)業(yè)各個(gè)部門和科學(xué)研究的各個(gè)領(lǐng)域所采用，成為人們從事生產(chǎn)和科研的有力測(cè)試手段。目前市場(chǎng)上有兩類主流產(chǎn)品:掃描光柵式分光光度計(jì)和固定光柵式分光光度計(jì)。 </p> <p> <br /> 國內(nèi)紫外可見分光光度計(jì)由于玻璃材質(zhì)會(huì)吸收紫外線，所以目前市面上的紫外可見分光光度計(jì)都采用石英棱鏡。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

定性定量。利用特定的吸收峰，快速對(duì)待測(cè)樣品進(jìn)行定性和定量分析。如聚六亞甲基雙胍鹽酸鹽的檢測(cè)。利用雙波長(zhǎng)，以很快的速度辨別是單胍還是雙胍，并進(jìn)行粗略定量。這是液相色譜無論如何也做不到的。 </p> <p> 測(cè)定透過率。透光率是一個(gè)物理詞匯，是表示光線透過介質(zhì)的的能力，是透過透明或半透明物體的光通量與其入射光通量的百分率。吸光度與透過率的換算公式 </p> <p> 透過率對(duì)于某些原料檢測(cè)是非常實(shí)用的，可對(duì)此類原料品質(zhì)進(jìn)行總體把控。 </p> <p> 雜質(zhì)的檢測(cè)。通過前處理將雜質(zhì)與主成分分離后，進(jìn)行紫外分光光度測(cè)定，可很快得到該雜質(zhì)的含量。以桑普實(shí)驗(yàn)室這十幾年對(duì)苯氧乙醇中雜質(zhì)苯酚的測(cè)定方法改進(jìn)過程為例： </p> <p> 之后建立了4-氨基安替比林比色法，可實(shí)現(xiàn)對(duì)苯氧乙醇含量20、40、60、80、100ppm的區(qū)分；紫外分光光度法 </p> <p> 期間同時(shí)采用EP中紫外分光光度法，并將其進(jìn)行適當(dāng)改進(jìn)，作為修訂后的企標(biāo)。該方法便利快速，可實(shí)現(xiàn)50ppm以上的定量檢測(cè)。HPLC-DAD </p> <p> 近兩年，桑普對(duì)產(chǎn)品品質(zhì)把控更嚴(yán)格，希望能實(shí)現(xiàn)幾個(gè)ppm的定量檢測(cè)。所以采用了HPLC-DAD作為企標(biāo)對(duì)其檢測(cè)。 </p><p> 如何正確使用752N紫外可見分光光度計(jì) </p> <p> A：在使用紫外可見分光光度計(jì)時(shí)候，設(shè)備儀器使用之前，一定需要能夠把樣品室內(nèi)存放的防潮劑給拿出來，且在設(shè)備正常運(yùn)轉(zhuǎn)檢查時(shí)候也不能開啟樣品室蓋；在檢查時(shí)候需注意比色皿當(dāng)中的液體要能占總體積的百分之六十六到百分之八十比較好，千萬不能讓液體太多以至于液體外泄直接腐蝕儀器設(shè)備。 </p> <p> 當(dāng)然在進(jìn)行正常檢測(cè)時(shí)候，也要能確保比色皿干凈，當(dāng)發(fā)現(xiàn)內(nèi)壁上有液滴就許使用專業(yè)的紙張給擦拭干凈，建議大家千萬不要使用手直接擦拭，以免造成對(duì)手的傷害。 </p> <p> B：在使用紫外可見分光光度計(jì)時(shí)，儀器設(shè)備在正常運(yùn)轉(zhuǎn)的時(shí)候，一定要嚴(yán)禁把液體溶劑給直接放置于儀器的表層上，如果發(fā)現(xiàn)有溶劑液體出現(xiàn)外泄的情況，一定要進(jìn)行及時(shí)的清潔和處理。 </p> <p> C：當(dāng)使用紫外可見分光光度計(jì)檢測(cè)完畢后，還需要能夠及時(shí)把比色皿內(nèi)的液體給妥善處理掉，并還需要能夠使用蒸餾水給徹底清潔干凈，同時(shí)將比色皿進(jìn)行倒置晾干處理；全部工作完成后還需把設(shè)備儀器電源給關(guān)閉，再將防潮劑放入到樣品室內(nèi)并做好防塵處理才好。紫外可見吸收光譜是由于分子中的某些基團(tuán)吸收了紫外可見輻射光后，發(fā)生了電子能級(jí)躍遷而產(chǎn)生的吸收光譜。</p><div

光柵實(shí)現(xiàn)上就是一系列等寬、等距離的平行狹縫，它是利用光的衍射與干涉作用制成的。光柵作為色散元件具有不少獨(dú)特的優(yōu)點(diǎn)，光柵單色器的分辨率比棱鏡單色器的分辨率高，可精確到0.2nm，而且可用的波長(zhǎng)范圍也比棱鏡單色器的范圍寬。所以，目前生產(chǎn)的紫外可見分光光度計(jì)大多采用光柵作為色散元件。 </p> <p> 吸收池是用于盛裝待測(cè)液并決定待測(cè)溶液透光液層厚度的器皿，又稱比色皿。吸收池一般為長(zhǎng)方體，也有圓形或其它形狀的。其底及兩側(cè)為毛玻璃，另兩面為光學(xué)透光面。根據(jù)光學(xué)透光面的材質(zhì)，吸收池又可分為玻璃吸收池和石英吸收池兩種。玻璃吸收池用于可見光區(qū)測(cè)定，石英吸收池用于紫外光區(qū)的測(cè)定。吸收池的規(guī)格以光程為標(biāo)志。常用的吸收池規(guī)格有0.5cm、1.0cm、2.0cm、3.0cm、5.0cm等。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。上海**紫外可見分光光度計(jì)生產(chǎn)廠家</p><p
