美國戴安 DIONEX   
戴安(DIONEX)公司成立于1975年，總部設在美國加州Sunnyvale，是世界上第一臺離子色譜的生產(chǎn)廠(chǎng)，二十多年來(lái)一直在離子色譜技術(shù)領(lǐng)域保持世界第一的位置。公司在美國、德國、荷蘭等國家都設有生產(chǎn)和研發(fā)部門(mén)。 戴安公司是納斯達克股票上市公司，為了配合中國加入WTO，進(jìn)一步拓展市場(chǎng)，為用戶(hù)提供直接的服務(wù)，DIONEX公司于2001年1月1日在中國北京和上海分別設立代表處，全權負責中國大陸地區的所有業(yè)務(wù)。同時(shí)在上海和北京建立技術(shù)服務(wù)中心和應用研究中心，負責中國用戶(hù)的售前售后服務(wù)及應用研發(fā)。

戴安公司生產(chǎn)的儀器主要有離子色譜儀、高效液相色譜儀、快速溶劑萃取儀和氨基酸直接分析儀。其中離子色譜儀憑借著(zhù)雄厚的技術(shù)優(yōu)勢和專(zhuān)利方法已廣泛地應用于各個(gè)領(lǐng)域，其市場(chǎng)占有率達80%。全球與離子色譜相關(guān)的文章有90%均出自戴安公司生產(chǎn)的離子色譜儀。

戴安公司專(zhuān)利的快速溶劑萃取儀15分鐘之內僅用15毫升溶劑既可完成對10g樣品的萃取，該技術(shù)已在環(huán)境、藥物、食品和聚合物工業(yè)等領(lǐng)域得到廣泛應用。

A Business Built on Solutions
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, accelerated solvent extraction (ASE), automation, and on-line process analysis.

An Emphasis on Quality
To maintain the highest possible level of quality, Dionex has established quality standards for every phase of our operation. All Dionex products are designed, developed, and manufactured under a registered ISO 9001 Quality System. We also encourage customer comments and collect them from every possible source. These comments give us a reading on customer satisfaction and provide the information we need to continue finding ways to improve the quality of our products and services.

Maintaining Technological Leadership
Innovation and quality have made Dionex a leader in the worldwide separations industry. Our expertise allows us to work closely with chemists, biochemists, and other customers in various markets. We actively seek new technologies to help our industry. Customer satisfaction is the foundation for our continued growth and strong financial condition. And it is the organizing principle for all of our operations, from R&D and manufacturing, to sales and customer support.

Meeting a Growing Need
As more chemists use our products, the range of customer needs expands, and so does the range of systems and services that we offer to meet those needs. Our products are used extensively for chemical analysis, sample preparation, and laboratory automation in the environmental, proteomics, life science/biotechnology, chemical, petrochemical, power generation, pharmaceutical, and electronics industries. Our customers include many of the world's largest companies, government agencies, research institutions, and universities.

Providing Solutions Worldwide
Dionex headquarters are located in Sunnyvale, California, in the heart of the dynamic high-technology community known as Silicon Valley. Our sales and service offices are located throughout the United States and our technical center is in Salt Lake City, Utah. Dionex International subsidiaries are located in Austria, Belgium, Canada, China, Denmark, France, Germany, Italy, Japan, the Netherlands, Switzerland, and the United Kingdom, with distributors in dozens of countries worldwide.
