ISO 10304 Determination of Anions in Water by Ion Chromatography
The ISO 10304 standard provides a precise and reliable method for determining anions in water samples using ion chromatography. This technique allows for the accurate quantification of various anions such as chloride, bromide, iodide, nitrate, nitrite, fluoride, and phosphate ions.
Ion chromatography is a form of liquid chromatography that separates charged species on the basis of differences in their affinity for an ion-exchange stationary phase. This method ensures high sensitivity and selectivity, making it particularly suitable for trace analysis in water samples.
The procedure involves several critical steps including sample preparation, conditioning, injection, and detection. Sample preparation typically requires filtering the water through a 0.45 μm filter to remove particulates that could interfere with the chromatographic process.
The conditioned sample is then introduced into the ion chromatography system where it passes through an anion exchange column. The ions in the solution are separated based on their affinity for the stationary phase, and they elute from the column at different times depending on their chemical properties.
Detection of the separated ions is achieved using a conductivity detector which measures changes in electrical conductance as the ions pass through it. The data collected is then analyzed to determine the concentration of each ion present in the sample.
The accuracy and precision of this method are enhanced by the use of certified reference materials (CRMs) and strict adherence to standard operating procedures (SOPs). This ensures that results can be reproduced consistently across different laboratories, making ISO 10304 a robust choice for regulatory compliance and quality assurance.
Compliance with this standard is crucial in sectors such as water treatment, environmental monitoring, pharmaceutical manufacturing, and food processing. In these industries, the presence of trace levels of anions can have significant implications on product safety and quality.
The use of ion chromatography for determining anions in water by ISO 10304 is widely recognized for its ability to provide reliable and accurate results. This method supports regulatory requirements such as those set out by the United States Environmental Protection Agency (EPA) and European Union Directives on drinking water quality.
