ISO 15923-1 Water Quality — Ion Chromatography for Nitrate

ISO 15923-1 Water Quality Ion Chromatography for Nitrate Laboratory Testing Service Provided by Eurolab

Standard-Related Information

ISO 15923-1 is an international standard that specifies the requirements for the determination of nitrate in water using ion chromatography (IC). This standard is part of the ISO 15923 series, which covers various aspects of water quality analysis. The standard was developed by the International Organization for Standardization (ISO) and published in 2017.

The standard is based on the principles of ion exchange chromatography and specifies the requirements for the equipment, reagents, and procedures used in the determination of nitrate in water samples. The standard also includes guidelines for the calibration, validation, and quality control of the analytical method.

Legislative and Regulatory Framework

The ISO 15923-1 standard is supported by various legislative and regulatory frameworks around the world. For example:
