戴安公司生产的仪器主要有离子色谱仪、高效液相色谱仪、快速溶剂萃取仪和氨基酸直接分析仪。其中离子色谱仪凭借着雄厚的技术优势和专利方法已广泛地应用于各个领域，其市场占有率达80%。全球与离子色谱相关的文章有90%均出自戴安公司生产的离子色谱仪。

戴安公司专利的快速溶剂萃取仪15分钟之内仅用15毫升溶剂既可完成对10g样品的萃取，该技术已在环境、药物、食品和聚合物工业等领域得到广泛应用。

纳升级高效液相色谱用于药物和生化筛选以及蛋白质组学研究，高灵敏度，高效率，微量，是飞行时间质谱做液-质联用的最佳配合装置。

戴安公司的氨基酸直接分析仪与传统的柱前柱后衍生法不同，采用直接进样（无需衍生），阴离子交换分离，脉冲积分安培检测器检测的方法。一次进样40分钟内可同时完成全部氨基酸和碳水化合物的分析。方法简单，灵敏度高，自动化操作，即时监控生产过程。

戴安公司重视对中国市场的技术推广，在介绍各种先进产品的同时有大量的技术资料提供给中国的用户，为及时了解国际先进技术和提高用户的技术水品提供了便利条件。

戴安公司为用户提供良好的售后服务和技术培训，确保用户的问题得到及时有效的解决。

戴安是世界离子色谱技术的先驱，拥有戴安就拥有世界一流的技术。

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.
