一直以來都認(rèn)為比色皿洗滌不干凈會造成很大實(shí)驗(yàn)誤差，才發(fā)現(xiàn)原來比色皿選擇不當(dāng)也能造成不可預(yù)測的誤差。在此，就小結(jié)下有關(guān)如何正確選擇比色皿、比色皿使用注意事項(xiàng)以及比色皿的洗滌方法。 </p> <p> 比色皿透光面是由能夠透過所使用的波長范圍的光的材料制成。在200-350nm工作的比色皿適用于紫外區(qū),必須使用石英或熔熔硅石制成透光面的石英比色皿。(注：熔熔硅石的還真沒見過，只用過石英的)石英比色皿既可用于紫外區(qū)又可用于可見區(qū)，但是價(jià)格一般比較貴，車載紫外可見分光光度計(jì)廠家，所以要根據(jù)使用波長選擇比色皿，如果不用紫外區(qū)的話，用普通玻璃比色皿就行了，一則浪費(fèi)沒必要，二則，嘿嘿，車載紫外可見分光光度計(jì)廠家，摔碎了也不心疼，哈哈，車載紫外可見分光光度計(jì)廠家。而普通硅酸鹽光學(xué)玻璃制成的透光面的比色皿,只能用于350nm至1000nm的可見區(qū)。金屬離子常與有機(jī)物形成絡(luò)合物，多數(shù)絡(luò)合物在紫外可見區(qū)是有吸收的，我們可以利用分光光度法來研究其組成。車載紫外可見分光光度計(jì)廠家</p><div

可見分光光度計(jì)和紫外分光光度計(jì)的區(qū)別是測定波長范圍不同，一般可見光波長范圍是400～1000nm,紫外光波長范圍是200～400nm。所謂紫外可見分光光度計(jì)也就是說這個儀器可以通過更換光源形成紫外和可見的光區(qū)，能夠測定吸收峰在紫外和可見光部分的化合物。一般測定波長在200～1000nm。 </p> <p> 分光光度計(jì)的關(guān)鍵參數(shù)有哪些? </p> <p> 選擇可見和紫外可見的分光光度計(jì)所關(guān)注的關(guān)鍵的指標(biāo)有三點(diǎn)：一是波長范圍，二是波長準(zhǔn)確度，三是雜散光參數(shù)。波長范圍的選擇是由用戶實(shí)驗(yàn)需要所定，波長范圍越寬的價(jià)格越貴;波長準(zhǔn)確度及雜散光參數(shù)的數(shù)值越低，表示性能越好。全自動紫外可見分光光度計(jì)廠家供應(yīng)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。</p><div

紫外可見分光光度計(jì)的特點(diǎn)分光光度法對于分析人員來說，可以說是常用和有效的工具之一。幾乎每一個分析實(shí)驗(yàn)室都離不開紫外可見分光光度計(jì)。分光光度法具有以下主要特點(diǎn)。 </p> <p> 1靈敏度高 </p> <p> 由于新的顯色劑的大量合成，并在應(yīng)用研究方面取得了可喜的進(jìn)展，使得對元素測定的靈敏度有所推進(jìn)，特別是有關(guān)多元絡(luò)合物和各種表面活性劑的應(yīng)用研究，使許多元素的摩爾吸光系數(shù)由原來的幾萬提高到數(shù)十萬。 </p> <p> 2選擇性好 </p> <p> 目前已有些元素只要利用控制適當(dāng)?shù)娘@色條件就可直接進(jìn)行光度法測定，如鈷、鈾、鎳、銅、銀、鐵等元素的測定，已有比較滿意的方法了。 </p> <p> 3準(zhǔn)確度高 </p> <p> 對于一般的分光光度法，其濃度測量的相對誤差在1～3%范圍內(nèi)，如采用示差分光光度法進(jìn)行測量，則誤差可減少到0.X%。 </p> <p> 4適用濃度范圍廣 </p> <p> 可從常量(1%～50%)(尤其使用示差法)到痕量(10-8～10-6%)(經(jīng)預(yù)富集后)。 </p> <p> 5分析成本低、操作簡便、快速、應(yīng)用廣 </p> <p> 由于各種各樣的無機(jī)物和有機(jī)物在紫外可見區(qū)都有吸收，因此均可借此法加以測定。到目前為止，幾乎化學(xué)元素周期表上的所有元素(除少數(shù)放射性元素和惰性元素之外)均可采用此法。在國際上發(fā)表的有關(guān)分析的論文總數(shù)中，光度法約占28%，我國約占所發(fā)表論文總數(shù)的33%。 </p><p> 常見的可見分光光度計(jì)和紫外可見分光光度計(jì)的型號有哪些? </p> <p> 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型相對于721是型將測試樣品室加寬，可用10cm的比色皿，為糖廠**檢測儀器。722系列可見分光光度計(jì)有722/722S/722N型，測定波長為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，測定波長為320-1000nm，其中723是手動調(diào)整波長，723N是自動調(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。紫外分光光度計(jì)儀器使用一定周期后，由維修工程師或在工程師指導(dǎo)下定期開啟儀器外罩對內(nèi)部進(jìn)行除塵工作。</p><div

分光光度計(jì)作為一種精密儀器，在運(yùn)行工作過程中由于工作環(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明，并能及時(shí)發(fā)現(xiàn)和排除這些隱患，對已產(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> 若大幅度改變測試波長，需稍等片刻，等燈熱平衡后，重新校正“0”和“100%”點(diǎn)。然后再測量。 </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)輕易動燈泡及反光鏡燈，以免影響光效率。傳統(tǒng)單光束UV紫外測試，測試過程全程封閉，單光束光源只通過光柵直接照射樣品，再經(jīng)光電倍增管檢測器檢測。車載紫外可見分光光度計(jì)廠家</p><p style="text-indent:25px">一般來說，紫外光分光光度計(jì)分為單光束和雙光束兩類。車載紫外可見分光光度計(jì)廠家</p><p> 紫外可見分光光度計(jì)條件設(shè)定 </p> <p> 在定量分析中，為了提高測定的靈敏度，入射光的波長應(yīng)選擇被測物的MAX吸收波長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，不僅能提高測定的靈敏度，還能提高測定的準(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)小于待測樣品吸收帶的半寬度，否則測得的吸光度值會偏低，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)，對于大部分被測品種，可以使用2nm縫寬。 </p> <p> 可通過控制被測物濃度或改變吸收池厚度來實(shí)現(xiàn)吸光度合理的范圍，以盡量減小測量誤差。一般吸光度盡量控制在0.1-0.8范圍。 </p> <p> 空白溶液是用來調(diào)節(jié)吸光度測量工作零點(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入射光的反射和吸收所帶來的誤差。根據(jù)情況不同，常用空白溶液有如下幾種選擇。
