使用紫外分光光度計的過程中，經(jīng)常會遇到儀器因光源達不到要求，需要進行調修。要求光源燈處不能有空氣流動，因為單光束儀器很忌諱空氣快速流動而使光源燈的色溫發(fā)生變化。如遇電壓正常而鎢燈不亮時，就需要更換鎢燈。更換時，不要用手直接接觸燈泡表面，如果手指摸過，應用無水乙醇和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整光路。光源燈有兩個引線頭，安裝時用導線焊接，主要是防止接觸不良而造成的光源發(fā)光不穩(wěn)現(xiàn)象。在焊接時防止焊點與燈頭銅皮碰上，裝上燈座使電源短路。燈絲要求平直，如果燈絲彎曲，會影響光能量。燈絲的位置要與入射狹縫平行并對準，上、下、左、右調節(jié)后緊固螺釘。擰緊燈座的螺紋套，可用鉗子擰緊，一般燈頭盡量往燈座里塞，因為多數(shù)燈絲離燈頭偏高。調整燈位置的前后可移動整個燈座架，它下面有三個固定螺釘，先稍松后，移動前后位置再固定。一般調節(jié)鎢燈的位置時，將波長調到580nm處，狹縫調到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；光斑左邊或右邊不完整，可調光源燈底座位置。調整至白紙上可見明亮、均勻的長方形黃橙色光斑。甲醛紫外可見分光光度計排行一般來說，紫外光分光光度計分為單光束和雙光束兩類。</p><div

style="text-indent:25px"><p>綜合評價紫外可見光分光光度計儀器：根據(jù)使用領域進行初步篩選，科研、制藥領域注重選擇光譜可調的紫外可見光分光光度計。其中，制藥中藥檢儀器要符合藥典規(guī)定，光譜帶寬要求為2nm以下。<p>重要性能指標的考察，包括：光度準確度，雜散光，光譜帶寬，穩(wěn)定性，噪聲，波長的準確度和重復性是幾個重要指標。各指標間相互獨立有相互影響，需要綜合考量選購目標紫外可見光分光光度計。<p>使用前，閱讀儀器使用說明書和做好儀器使用前的工程師培訓。使用過程中，正確操作、認真了解儀器指標的物理意義和測試方法以及結合儀器使用中的相關設備的調試。掌握儀器的基本保養(yǎng)維護知識，建立相關指標與分析測試結果之間的誤差影響條件，經(jīng)常檢測和調試儀器，確保儀器處在合適的工作狀態(tài)。</p><p> 紫外可見分光光度計的發(fā)展分光光度法在分析領域中的應用已經(jīng)有數(shù)十年的歷史，至今仍是應用常用的分析方法之一。隨著分光元器件及分光技術、檢測器件與檢測技術、大規(guī)模集成制造技術等的發(fā)展，以及單片機、微處理器、計算機和DSP技術的應用，分光光度計的性能指標不斷提高，并向自動化、智能化、高速化和小型化等方向發(fā)展。 </p> <p> 在分光元器件方面，經(jīng)歷了棱鏡、機刻光柵和全息光柵的過程，商品化的全息閃耀光柵已迅速取代一般刻劃光柵。在儀器控制方面，隨著單片機、微處理器的出現(xiàn)以及軟硬件技術的結合，從早期的人工控制進步到了自動控制。在顯示、記錄與繪圖方面，早期采用表頭(電位計)指示、繪圖儀繪圖，后來用數(shù)字電壓表數(shù)字顯示，如今更多地采用液晶屏幕或計算機屏幕顯示。在檢測器方面，早期使用光電池、光電管，后來更普遍地使用光電倍增管甚至光電二極管陣列。陣列型檢測器和凹面光柵的聯(lián)合應用，使儀器的測量速度發(fā)生了質的飛躍，且性能更加穩(wěn)定可靠，受到儀器用戶的青睞，在儀器構型方面，從單光束發(fā)展為雙光束，現(xiàn)在幾乎所有高級分光光度計都是雙光束的，有些高精度的儀器采用雙單色器。紫外可見分光光度計，可以通過更換光源分別形成可見和紫外光區(qū)，測定的波長在200～1000nm。</p><div

俺的經(jīng)驗是：要是你測定溶液是酸，如果不干凈，就用弱堿溶液洗，要是你測定溶液是堿，如果不干凈，就用弱酸溶液洗，要是你測定溶液是有機物質，如果不干凈，就用有機溶劑，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，同時又不影響測定。 </p> <p> 2.1分析常用的鉻酸洗液不宜用于洗滌比色皿，這是因為帶水的比色皿在該洗液中有時會局部發(fā)熱，致使比色皿膠接面裂開而損壞。同時經(jīng)洗液洗滌后的比色皿還很可能殘存微量鉻，其在紫外區(qū)有吸收，因此會影響鉻及其他有關元素的測定。 </p> <p> 一般主張使用硝酸和過氧化氫(5：1)的混合溶液泡洗，然后用水沖洗干凈。對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，再于過氧化氫和硝酸(5：1)混合溶液中侵泡半小時。在大部分的樣品類型中，分光光度計可接受樣品孔、小玻璃管cuvette、吸漿管和微孔板。甲醛紫外可見分光光度計排行</p><p style="text-indent:25px">例如測試紫外區(qū)時則可關閉紫外分光光度計鎢燈；反之關閉氘燈。這樣就延長了那只不使用的光源燈的壽命。國產(chǎn)紫外可見分光光度計生產(chǎn)廠家</p><p style="text-indent:25px">使用紫外可見分光光度計進行定量和定性分析需注意以下一些問題：1吸光度讀數(shù)范圍：吸光度測量誤差在透過率過大或過小時都會變大，為了滿足定量分析的誤差要求（<5%），在定量分析時要求吸光度應在一定的范圍內(nèi)，這個范圍的具體值與儀器性能有關，主要是與紫外可見分光光度計檢測系統(tǒng)噪聲大小有關，但通常都在0.1~1.0范圍內(nèi)，如果儀器的檔次更低，則范圍更窄。根據(jù)朗伯比爾定律，影響吸光度大小的因素主要是樣品摩爾吸光系數(shù)，濃度和比色皿光程。實驗中吸光度過大的樣品可通過稀釋樣品使吸光度到所需范圍內(nèi)。如果樣品不能稀釋，可以改用光程較小的比色皿減小吸光度。吸光度過小的樣品可使用光程較大的比色皿以增大吸光度。國產(chǎn)紫外可見分光光度計生產(chǎn)廠家</p><p
