主要特点:
ASE使用常见溶剂在加温加压下提取样品,大大提高萃取效率,减少溶剂消耗。ASE技术使戴安跻身到世界溶剂萃取技术的领先地位。已开发的ASE方法广泛应用于环境、医药、食品、聚合物以及消费品工业。ASE被美国EPA方法3545A和6860,以及美国材料测试学会的ASTM D 7210所采用。
在高温高压下进行溶剂萃取的优势:
●提高分析物的溶解能力
-降低溶剂粘度,使溶剂分子更易进入样品基质
-提高分子运动的能力,使分析物更
易挣脱基质的束缚
-提高分散能力,使分析物更易扩散 人溶剂中
●增加压力使溶剂在萃取过程中一直保 持液态
最新D i o n i u m TM材质的流路设计,极大地扩展应用范围
全新设计的DioniumTM流路,具有化学惰性,使新的ASE能直接萃取经过酸碱处理的样品,极大的扩展了ASE的应用范围。

戴安公司成立于1975年(纳斯达克股票:DNEX),位于美国硅谷Sunnyvale。公司奋斗目标是不断为全球化学工作者提供高科技产品,帮助减少繁复而耗时的实验室工作环节。公司成立同年,戴安公司发明了世界第一台离子色谱,该项革命性的分析技术使得全球化学工作者能够从混合物中快速分离鉴别出各项离子成分。历经几十年的发展,到目前为止戴安各项成熟技术已被大大扩展,包括离子色谱仪IC(全球市场份额80%),高效液相色谱HPLC包括毛细管和微流量液相色谱Nano-LC(全球市场份额40%),氨基酸直接分析仪AAA-Direct,快速溶剂萃取仪ASE和固相萃取仪Autotrace及在线分析仪器等。
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
