美國(guó)麥克儀器 2011-11-22 | 閱讀：4763

自美國(guó)麥克儀器公司AutoChem系列研究級(jí)高性能全自動(dòng)程序升溫化學(xué)吸附儀問(wèn)世以來(lái),，憑借其過(guò)硬的技術(shù)優(yōu)勢(shì)引領(lǐng)化學(xué)吸附技術(shù)發(fā)展方向,，解決用戶化學(xué)吸附測(cè)試中的難題，并逐漸成為化學(xué)吸附分析的領(lǐng)導(dǎo)者,。麥克儀器公司始終追隨客戶的需求,，不斷升級(jí)改進(jìn)自己的技術(shù),， AutoChem 系列儀器已經(jīng)經(jīng)過(guò)了幾代的升級(jí)演變,。自AutoChem II 2920發(fā)布至今,，它已經(jīng)成為全球各個(gè)著名大學(xué)以及研究結(jié)構(gòu)的首選儀器。其中不乏中國(guó)知名學(xué)府和研究院,，華東理工,、華南理工、天津大學(xué),、復(fù)旦大學(xué),、廈門大學(xué)、北京科技大學(xué),、北京工業(yè)大學(xué),、北京化工研究院、中石化石油化工科學(xué)研究院,、中科院大連化物所,、中海油天津化工研究院、蘭州石油化工研究院,、上海石油化工研究院等等都是AutoChem II2920的用戶,。

AutoChem II 2920具有如下技術(shù)特征：

4個(gè)內(nèi)部溫度控制區(qū)可獨(dú)立加熱，最高達(dá)250 ℃（TCD）,。這樣可以防止氣體在流動(dòng)過(guò)程中凝結(jié)與吸附,。
小體積的內(nèi)部管路保證了高分辨率與快速探測(cè)器響應(yīng)，并在計(jì)算氣體體積時(shí)減少錯(cuò)誤,。
高度敏感的線性熱傳導(dǎo)檢測(cè)器（TCD ）確保校準(zhǔn)體積在整個(gè)峰范圍內(nèi)保持恒定,，從而峰面積與反應(yīng)氣體體積成正比關(guān)系
四個(gè)高精度的質(zhì)量流量控制器提供非常準(zhǔn)確、可程序控制的氣體流量控制,，保證了穩(wěn)定的基線和氣體體積的準(zhǔn)確測(cè)定,。
鍍金TCD具有超強(qiáng)抗氨腐蝕性和抗氧化性，從而盡可能降低檢測(cè)器損耗,。
開(kāi)合式加熱爐能加熱石英樣品反應(yīng)器到1100℃ ,。可設(shè)定任意數(shù)量的升溫速率和內(nèi)置方法,，方便定制的實(shí)驗(yàn),。 KwikCool功能冷卻爐可使?fàn)t內(nèi)溫度迅速下降到環(huán)境溫度，減少分析時(shí)間,，提高測(cè)試量,。
分別用于制備、載氣和LOOP氣的十二路進(jìn)氣口允許連接更多的氣體,，進(jìn)行更為復(fù)雜的實(shí)驗(yàn),。例如TPR / TPO循環(huán),。
質(zhì)譜儀端口和集成軟件允許同時(shí)在熱導(dǎo)檢測(cè)器和質(zhì)譜儀上進(jìn)行檢測(cè)。
蒸汽發(fā)生器允許蒸汽吸附反應(yīng),，例如吡啶,、苯和水。
CryoCooler冷浴槽可以在-110℃低溫條件下開(kāi)始進(jìn)行反應(yīng),，滿足貴金屬催化反應(yīng)研究,。
同時(shí)AutoChem II 2920也可以根據(jù)客戶實(shí)際需要進(jìn)行各種定制。
