Determination of Inorganic Anions in Environmental Water Using a Hydroxide Selective Column
11 Nov 2016Ion chromatography is a well-established and accepted technique for monitoring inorganic anions in environmental waters. This application notes describes the use of automated eluent generation, combined with a high-capacity hydroxide selective, anion exchange column, Dionex IonPac® AS18, for the determination of inorganic anions in environmental waters.

Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Inorganic AnionsWater AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.Drinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).
