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廠，二十多年來一直在離子色譜技術領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和研發部門。 戴安公司是納斯達克股票上市公司，為了配合中國加入WTO，進一步拓展市場，為用戶提供直接的服務，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務。同時在上海和北京建立技術服務中心和應用研究中心，負責中國用戶的售前售后服務及應用研發。

戴安公司生產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雄厚的技術優勢和專利方法已廣泛地應用于各個領域，其市場占有率達80%。全球與離子色譜相關的文章有90%均出自戴安公司生產的離子色譜儀。

戴安公司專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，該技術已在環境、藥物、食品和聚合物工業等領域得到廣泛應用。

納升級高效液相色譜用于藥物和生化篩選以及蛋白質組學研究，高靈敏度，高效率，微量，是飛行時間質譜做液-質聯用的最佳配合裝置。

戴安公司的氨基酸直接分析儀與傳統的柱前柱后衍生法不同，采用直接進樣（無需衍生），陰離子交換分離，脈沖積分安培檢測器檢測的方法。一次進樣40分鐘內可同時完成全部氨基酸和碳水化合物的分析。方法簡單，靈敏度高，自動化操作，即時監控生產過程。

戴安公司重視對中國市場的技術推廣，在介紹各種先進產品的同時有大量的技術資料提供給中國的用戶，為及時了解國際先進技術和提高用戶的技術水品提供了便利條件。

戴安公司為用戶提供良好的售后服務和技術培訓，確保用戶的問題得到及時有效的解決。

戴安是世界離子色譜技術的先驅，擁有戴安就擁有世界一流的技術。

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.
