Analysis of Inorganic Anions in Drinking Water According to EPA Method 300.1 Using Nexera IC -Part A

User Benefits

- Nexera IC system is suitable for analyzing drinking water in compliance with EPA Method 300.1 (Part A). - Utilizing optimized conditions for the Shim-pack IC SA3 allows for the separation of seven inorganic anions in under 20 minutes. - Employing an electrodialytic suppressor with superior baseline suppression enables highly sensitive analysis.

Introduction

Reliable determination of inorganic anions in drinking water is essential for regulatory compliance and protection of public health. In the United States, the Environmental Protection Agency (EPA) provides methods for the analysis of inorganic anions in water by ion chromatography in Method 300.11) (EPA Method 300.1). The anion suppressor installed in Nexera IC is designed to improve sensitivity by replacing sodium ions in the eluent with hydrogen ions before detection. In this report, we introduce examples of analysis of seven inorganic anions in accordance with EPA Method 300.1 Part A using the Nexera IC.
