紫外分(fen)(fen)光(guang)光(guang)度計，就是根(gen)據(ju)物質(zhi)的(de)吸(xi)(xi)(xi)收光(guang)譜(pu)研究物質(zhi)的(de)成分(fen)(fen)、結構和(he)物質(zhi)間(jian)相(xiang)互(hu)作(zuo)用的(de)有(you)(you)效手段。紫外分(fen)(fen)光(guang)光(guang)度計可(ke)以在紫外可(ke)見光(guang)區任意(yi)選擇(ze)不(bu)同(tong)波長(chang)的(de)光(guang)。物質(zhi)的(de)吸(xi)(xi)(xi)收光(guang)譜(pu)就是物質(zhi)中的(de)分(fen)(fen)子(zi)和(he)原子(zi)吸(xi)(xi)(xi)收了入射光(guang)中的(de)某些特定(ding)波長(chang)的(de)光(guang)能量，相(xiang)應地發生了分(fen)(fen)子(zi)振動能級躍遷和(he)電子(zi)能級躍遷的(de)結果(guo)。由于各種物質(zhi)具(ju)有(you)(you)各自不(bu)同(tong)的(de)分(fen)(fen)子(zi)、原子(zi)和(he)不(bu)同(tong)的(de)分(fen)(fen)子(zi)空間(jian)結構，其(qi)吸(xi)(xi)(xi)收光(guang)能量的(de)情況也(ye)就不(bu)會相(xiang)同(tong)，因此，每種物質(zhi)就有(you)(you)其(qi)特有(you)(you)的(de)、固定(ding)的(de)吸(xi)(xi)(xi)收光(guang)譜(pu)曲線，可(ke)根(gen)據(ju)吸(xi)(xi)(xi)收光(guang)譜(pu)上的(de)某些特征波長(chang)處的(de)吸(xi)(xi)(xi)光(guang)度的(de)高低(di)判別(bie)或測定(ding)該物質(zhi)的(de)含量。

UV752型紫(zi)外(wai)可見分光(guang)(guang)光(guang)(guang)度計可廣泛應用于醫(yi)藥衛生(sheng)、臨床檢(jian)(jian)驗、生(sheng)物(wu)化學、石油(you)化工、環境保護、質(zhi)量控制、司(si)法刑偵、檢(jian)(jian)驗檢(jian)(jian)疫林業(ye)、地質(zhi)勘(kan)探、食品(pin)檢(jian)(jian)測等行業(ye),是理化實(shi)驗室(shi)常用的(de)分析儀(yi)器之(zhi)一。

應用(yong)：利(li)用(yong)分光(guang)光(guang)度法對PCB制成中物(wu)質進行定(ding)(ding)(ding)量定(ding)(ding)(ding)性分析。而分光(guang)光(guang)度法則是通(tong)過測(ce)定(ding)(ding)(ding)被測(ce)PCB各種元素(su)在特定(ding)(ding)(ding)波長處或一定(ding)(ding)(ding)波長范圍(wei)內(nei)光(guang)的吸收度，對該PCB元素(su)進行分析定(ding)(ding)(ding)量或定(ding)(ding)(ding)型(xing)分析。特點：具(ju)有操(cao)作簡單，維護方便，數據(ju)準確等特點。
