紫外老化試驗(yàn)箱可見分光光度計(jì)的*保養(yǎng)方法

分析儀器工作者要懂得儀器的日常維護(hù)和對(duì)主要技術(shù)指標(biāo)的簡易測試方法，自己經(jīng)常對(duì)儀器進(jìn)行維護(hù)和測試，以保證儀器工作在*狀態(tài)。

一、溫度和濕度是影響儀器性能的重要因素。他們可以引起機(jī)械部件的銹蝕，使金屬鏡面的光潔度下降，引起儀器機(jī)械部分的誤差或性能下降；造成光學(xué)部件如光柵、反射鏡、聚焦鏡等的鋁膜銹蝕，產(chǎn)生光能不足、雜散光、噪聲等，甚至儀器停止工作，從而影響儀器壽命。維護(hù)保養(yǎng)時(shí)應(yīng)定期加以校正。應(yīng)具備四季恒濕的儀器室，配置恒溫設(shè)備，特別是地處南方地區(qū)的實(shí)驗(yàn)室。

二、環(huán)境中的塵埃和腐蝕性氣體亦可以影響機(jī)械系統(tǒng)的靈活性、降低各種限位開關(guān)、按鍵、光電偶合器的可靠性，也是造成必須學(xué)部件鋁膜銹蝕的原因之一。因此必須定期清潔，保障環(huán)境和儀器室內(nèi)衛(wèi)生條件，防塵。。

三、儀器使用一定周期后，內(nèi)部會(huì)積累一定量的塵埃，由維修工程師或在工程師指導(dǎo)下定期開啟儀器外罩對(duì)內(nèi)部進(jìn)行除塵工作，同時(shí)將各發(fā)熱元件的散熱器重新緊固，對(duì)光學(xué)盒的密封窗口進(jìn)行清潔，必要時(shí)對(duì)光路進(jìn)行校準(zhǔn)，對(duì)機(jī)械部分進(jìn)行清潔和必要的潤滑，zui后，恢復(fù)原狀，再進(jìn)行一些必要的檢測、調(diào)校與記錄。

Ultraviolet aging test chamber the best maintenance method of spectrophotometer

Analysis instrument workers should understand the instrument daily maintenance and simple test method of the main technical indicators, they often to maintenance and testing instruments, to ensure the instruments work in the best state.

A, temperature and humidity are the important factors influencing the device performance. They can cause mechanical parts of metal corrosion of mirror finish, or mechanical part of instrument error caused by performance degradation; Cause optical components such as grating, reflector, focusing mirror, such as corrosion of aluminum film, create light and stray light, noise, etc., and even equipment to stop working, thus affecting the service life of the instrument. Correction should be regular maintenance. Should have the four seasons and humidity instrument room, with a ?
