可見(jiàn)分光光度計(jì)常見(jiàn)的有721系列，722系列和723系列。721系列可見(jiàn)分光光度計(jì)有721/721-100型，測(cè)定波長(zhǎng)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(jiàn)分光光度計(jì)有722/722S/722N型，雙光束紫外可見(jiàn)分光光度計(jì)廠家供應(yīng)，測(cè)定波長(zhǎng)為330-1000nm/325-1000nm，雙光束紫外可見(jiàn)分光光度計(jì)廠家供應(yīng)。722型波長(zhǎng)是330-1000nm，722S與722N的波長(zhǎng)范圍325-1000nm，其中722N是自動(dòng)調(diào)節(jié)波長(zhǎng)。723系列可見(jiàn)分光光度計(jì)有723/723N/723PC/723PCS型四種，測(cè)定波長(zhǎng)為320-1000nm，其中723是手動(dòng)調(diào)整波長(zhǎng)，723N是自動(dòng)調(diào)波長(zhǎng)，723PC配有掃描軟件，雙光束紫外可見(jiàn)分光光度計(jì)廠家供應(yīng)，723PCS帶有掃描軟件和打印機(jī)。紫外可見(jiàn)分光光度計(jì)常見(jiàn)的是UV752/UV752N，波長(zhǎng)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(jiàn)吸收光譜是由于分子中的某些基團(tuán)吸收了紫外可見(jiàn)輻射光后，發(fā)生了電子能級(jí)躍遷而產(chǎn)生的吸收光譜。雙光束紫外可見(jiàn)分光光度計(jì)廠家供應(yīng)</p><div

</p> <p> 紫外分光光度計(jì)狹縫的大小會(huì)影響到儀器的信噪比和標(biāo)準(zhǔn)曲線的線性范圍。狹縫過(guò)大，通常會(huì)使線性范圍變小，特別是當(dāng)不在MAX吸收波長(zhǎng)位置測(cè)定時(shí)更是如此。狹縫過(guò)小，信噪比變差，基線平直度和測(cè)量數(shù)據(jù)的重復(fù)性會(huì)變差。此外，還需要考慮樣品吸收峰寬度的影響。通常單波長(zhǎng)測(cè)定時(shí)，一般選擇在MAX吸收波長(zhǎng)位置，線性范圍容易滿(mǎn)足，可選擇較寬的狹縫（1~2nm）多波長(zhǎng)測(cè)定時(shí)，很難同時(shí)在所有波長(zhǎng)都滿(mǎn)足線性范圍要求，應(yīng)選擇比較小的狹縫。國(guó)內(nèi)**紫外可見(jiàn)分光光度計(jì)比較分光光度計(jì)的氘燈和汞燈是在不同波長(zhǎng)的時(shí)候有程序控制自動(dòng)變換的，一般是在360nm處變換。</p><div

當(dāng)以空白試劑為參比調(diào)節(jié)儀器零點(diǎn)時(shí)，比色皿窗材料的吸收、內(nèi)外窗面的散射以及溶劑的吸收等都被抵消，所得吸光度值完全由顯色溶液中待測(cè)離了濃度所決定。此時(shí)吸光度值與試液濃度一般呈線性關(guān)系。吸光度值與測(cè)定濃度不成直線關(guān)系，發(fā)生向下彎曲(負(fù)偏離)或向上彎曲(正偏離)的現(xiàn)象而偏離朗伯一比爾定律的主要原因如下。 </p> <p> <br /> </p> <p> (1)非單色光的影響：紫外一可見(jiàn)分光光度訃使用連續(xù)光源和分光器分光，不可能得到真正理想的單色光；為保證在測(cè)量中能得到充分的光強(qiáng)，儀器必須保持一定的狹縫寬度。由狹縫射出后投射到被測(cè)物質(zhì)上的光，是一個(gè)有限寬度的譜帶——光譜通帶。隨光譜通帶寬度的增大，吸收光譜的分辨率降低，并偏離朗伯一比爾定律。 </p> <p> (2)非吸收光的影響：當(dāng)來(lái)自出射狹縫的光的光譜通帶寬度大于吸收光譜譜帶時(shí)，投射在被測(cè)物質(zhì)上的光就含有非吸收光。這不僅能使靈敏度降低，且能使校準(zhǔn)曲線向橫坐標(biāo)軸彎曲而偏離朗伯一比爾定律。按所吸收光的波長(zhǎng)區(qū)域不同，分為紫外分光光度法和可見(jiàn)分光光度法，合稱(chēng)為紫外-可見(jiàn)分光光度法。</p><div

</p> <p> 俺的經(jīng)驗(yàn)是：要是你測(cè)定溶液是酸，如果不干凈，就用弱堿溶液洗，要是你測(cè)定溶液是堿，如果不干凈，就用弱酸溶液洗，要是你測(cè)定溶液是有機(jī)物質(zhì)，如果不干凈，就用有機(jī)溶劑，比如酒精等溶液洗。 </p> <p> 2選擇比色皿洗滌液的原則是去污效果好，不損壞比色皿，同時(shí)又不影響測(cè)定。 </p> <p>

一般主張使用硝酸和過(guò)氧化氫(5：1)的混合溶液泡洗，然后用水沖洗干凈。對(duì)一般方法難以洗凈的比色皿，還可以采取以下兩種方法。 </p> <p> 2.2先將比色皿侵入含有少量陰離子表面活性劑的碳酸鈉(20克/升)溶液泡洗，經(jīng)水沖洗后，再于過(guò)氧化氫和硝酸(5：1)混合溶液中侵泡半小時(shí)。分光光度計(jì)元器件方面，經(jīng)歷了棱鏡、機(jī)刻光柵和全息光柵，商品化的全息閃耀光柵已迅速取代一般刻劃光柵。雙光束紫外可見(jiàn)分光光度計(jì)廠家供應(yīng)</p><p
