主要特點(diǎn):
ASE使用常見(jiàn)溶劑在加溫加壓下提取樣品,大大提高萃取效率,減少溶劑消耗。ASE 350應(yīng)用已被認(rèn)可的ASE技術(shù)。ASE技術(shù)使戴安躋身到世界溶劑萃取技術(shù)的領(lǐng)先地位。已開(kāi)發(fā)的ASE方法廣泛應(yīng)用于環(huán)境、醫(yī)藥、食品、聚合物以及消費(fèi)品工業(yè)。ASE被美國(guó)EPA方法3545A和6860,以及美國(guó)材料測(cè)試學(xué)會(huì)的ASTM D 7210所采用。
在高溫高壓下進(jìn)行溶劑萃取的優(yōu)勢(shì):
●提高分析物的溶解能力
-降低溶劑粘度,使溶劑分子更易進(jìn)入樣品基質(zhì)
-提高分子運(yùn)動(dòng)的能力,使分析物更
易掙脫基質(zhì)的束縛
-提高分散能力,使分析物更易擴(kuò)散 人溶劑中
●增加壓力使溶劑在萃取過(guò)程中一直保 持液態(tài)
最新D i o n i u m TM材質(zhì)的流路設(shè)計(jì),極大地?cái)U(kuò)展應(yīng)用范圍
全新設(shè)計(jì)的DioniumTM流路,具有化學(xué)惰性,使新的ASE能直接萃取經(jīng)過(guò)酸堿處理的樣品,極大的擴(kuò)展了ASE的應(yīng)用范圍。
高容量,高靈活性以及高效率
ASE350萃取儀可處理1-100g樣品。ASE350完全集合了ASE200和ASE300的功能,與溶劑控制器集成在一起,減小了工作臺(tái)的體積。350都配置快速泵(70 mL/mln),可提高工作效率。

戴安公司成立于1975年(納斯達(dá)克股票:DNEX),位于美國(guó)硅谷Sunnyvale。公司奮斗目標(biāo)是不斷為全球化學(xué)工作者提供高科技產(chǎn)品,幫助減少繁復(fù)而耗時(shí)的實(shí)驗(yàn)室工作環(huán)節(jié)。公司成立同年,戴安公司發(fā)明了世界第一臺(tái)離子色譜,該項(xiàng)革命性的分析技術(shù)使得全球化學(xué)工作者能夠從混合物中快速分離鑒別出各項(xiàng)離子成分。歷經(jīng)幾十年的發(fā)展,到目前為止戴安各項(xiàng)成熟技術(shù)已被大大擴(kuò)展,包括離子色譜儀IC(全球市場(chǎng)份額80%),高效液相色譜HPLC包括毛細(xì)管和微流量液相色譜Nano-LC(全球市場(chǎng)份額40%),氨基酸直接分析儀AAA-Direct,快速溶劑萃取儀ASE和固相萃取儀Autotrace及在線分析儀器等。
Dionex Corporation was founded in 1975 with the goal of helping chemists become more productive by providing them with products that eliminate repetitive, time-consuming tasks. At the time, Dionex was developing ion chromatography (IC), an innovative analytical technique that enabled chemists to quickly separate, isolate, and identify ionic components of chemical mixtures. Since then, the scope of Dionex technology has expanded to include a broad range of techniques, including IC, high-performance liquid chromatography (HPLC) including capillary and nano LC, AAA-Direct,accelerated solvent extraction (ASE), automation, and on-line process analys
