Water Analysis

Everyone in the global community is impacted by the quality of water resources. The water we drink must be free from harmful chemicals to ensure good health. The purity of ground and surface waters in our environment is critical to ensuring sustainable use. The water discharged by municipal waste water treatment plants and industrial facilities must be monitored to ensure strict compliance with environmental guidelines. Process waters must be kept clean from contaminants to ensure product quality and acceptable exposure levels.

Dionex is committed to enhancing the quality of our global water resources. As innovation leaders in ion and liquid chromatography, our analytical instruments are used by government and industry to provide solutions for environmental water testing for a wide range of regulated and emerging inorganic elements and organic compounds. For an overview of our environmental water analysis capabilities, please download our brochure Water Analysis for a Global Market.

As  pioneers of suppression technology, Dionex started a revolution in ion chromatography (IC) that increased the sensitivity and accuracy of ion determination. As constant innovators, we developed Reagent-Free™ IC (RFIC™) systems that set a new benchmark for ion analysis. Today, RFIC systems with Eluent Generation and Eluent Regeneration provide the ultimate in sensitivity and ease of use.

We also have a full HPLC product line for the analysis of organic contaminants, from nano- to preparative-scale separation capabilities, including UHPLC. 

In fact, we are the only separations science company that provides instrumentation, columns, and applications perfectly suited for both inorganic and organic contaminants.

Ground and Surface Water

Dionex has worked closely with the US EPA Office of Ground Water and Drinking Water to develop several methods. This collaboration has strengthened with the development of unique technology, including electrolytic suppression, and Reagent-Free™ IC (RFIC™) with Eluent Generation or Eluent Regeneration.

Drinking and Bottled Water

Regulatory agencies around the world have developed standards for water analysis and have provided guidance on water disinfection to assure drinking water quality. Dionex provides a variety of solutions for inorganic and organic drinking water contaminants.


Treating and recycling wastewater requires careful analysis and monitoring, including the determination of low-level contaminants such as pharmaceuticals and personal care products (PCP's). Dionex HPLC and IC instruments are well suited to determine a wide range of nonpolar, polar, and ionic contaminants.

Process Waters

Clean process water improves product efficiency, reduces waste, and makes more water available for drinking. One common occurrence in process waters that hinders efficiency is the presence of scale deposits on the interior pipe surfaces of steam boilers.

Water Analysis Regulations

Water regulations address the analyte or contaminant, the maximum contaminant level (MCL), and the analytical method(s) that can be used to quantify the contaminant.
