紫外分光光度計應用于農業檢測的主要用途

01引言

紫外分光光度計基本(ben)工(gong)作原理和紅(hong)外光(guang)(guang)譜(pu)儀相似，利(li)用一定頻率的紫外可(ke)見光(guang)(guang)照射被(bei)分析的有(you)機(ji)物質,引(yin)起分子中價電(dian)子的躍遷,它將有(you)選擇地(di)被(bei)吸收。一組吸收隨波(bo)長而(er)變化(hua)的光(guang)(guang)譜(pu),反映了試樣的特征。在(zai)紫外可(ke)見光(guang)(guang)的范圍內(nei),對于一個(ge)特定的波(bo)長，吸收的程度正比(bi)于試樣中該成分的濃(nong)度,因此測量光(guang)(guang)譜(pu)可(ke)以進行(xing)定性分析，而(er)且根據吸收與已知濃(nong)度的標樣的比(bi)較，還(huan)能進行(xing)定量分析。

02主要用途

04紫外分光光度計的選擇

我們在(zai)(zai)選擇各(ge)種儀器(qi)時，都有(you)一(yi)定的(de)標準(zhun)，如測量精度、或者測量范圍。而在(zai)(zai)選擇紫外分(fen)光光度計時，我們考(kao)慮(lv)的(de)是光學構造、光譜范圍、樣(yang)品類型和分(fen)析工具。

光學構造主要是指(zhi)紫外分光(guang)(guang)光(guang)(guang)度(du)計(ji)給出的光(guang)(guang)是單(dan)光(guang)(guang)束(shu)還是雙(shuang)光(guang)(guang)束(shu)。單(dan)光(guang)(guang)束(shu)是通過(guo)(guo)單(dan)束(shu)光(guang)(guang)進(jin)行測量(liang)，在(zai)測量(liang)過(guo)(guo)程中給定波長，然后通過(guo)(guo)被測物和對照物得到吸(xi)光(guang)(guang)結果。而雙(shuang)光(guang)(guang)束(shu)是通過(guo)(guo)一(yi)個(ge)斬光(guang)(guang)輪將光(guang)(guang)束(shu)一(yi)分為二(er)。

光源包括紅外線(xian)、紫(zi)外線(xian)和可(ke)見(jian)光。鎢燈和鹵素燈一般只覆蓋可(ke)見(jian)光部分(大約380 nm到800 nm)。而氙燈則可(ke)以覆蓋紫(zi)外光和可(ke)見(jian)光區(qu)域。

分光(guang)(guang)光(guang)(guang)度計通常(chang)使(shi)用光(guang)(guang)電倍增管(guan)和光(guang)(guang)敏二極管(guan)來測量(liang)吸光(guang)(guang)值。

在大部分(fen)的樣品(pin)類型中，分(fen)光光度計(ji)可(ke)接(jie)受(shou)樣品(pin)孔(kong)、小玻璃管cuvette、吸漿管和(he)微孔(kong)板(ban)。

大部分單機(ji)型的(de)(de)分光(guang)光(guang)度(du)計包含了驅動儀器(qi)運(yun)行(xing)和(he)管理數據的(de)(de)軟件。高性能的(de)(de)儀器(qi)，通常(chang)與PC機(ji)一起聯(lian)用，需要從制造(zao)商提供額外的(de)(de)軟件。同時(shi)用戶也可以選擇(ze)升級軟件以滿(man)足他們的(de)(de)需要。
