ISO 10304 Ion Chromatography Testing for Anions in Water
The ISO 10304 standard is a cornerstone of water quality testing specifically targeting anion species, which are negatively charged ions. This service involves analyzing various anions present in water samples using ion chromatography. The primary aim is to ensure compliance with international standards and to provide accurate data for quality management and R&D purposes.
The method is highly sensitive and can detect a wide range of anions including chloride, bromide, fluoride, nitrate, nitrite, phosphate, carbonate, silicate, and others. Compliance testing in the water sector ensures that potable water meets strict standards set by regulatory bodies like the World Health Organization (WHO) and US Environmental Protection Agency (EPA).
The process begins with the collection of water samples from various sources such as rivers, lakes, and municipal supplies. Samples are then prepared for analysis according to ISO 10304 guidelines. This involves dilution if necessary and filtration to remove particulate matter that could interfere with chromatographic separation.
Upon sample preparation, the process moves into the chromatography phase where the anions are separated based on their unique retention times in a column packed with stationary phases designed for ion exchange. The eluents used play a crucial role in this process, as they must be optimized to ensure effective separation and detection.
The detected ions are quantified using a UV-visible detector or conductivity detector depending on the specific anions being targeted. The results provide detailed concentration data that can be used for quality assurance purposes, compliance reporting, and research into water treatment methods.
Our laboratory adheres strictly to ISO 10304 standards during every step of this process ensuring reliability and accuracy in our findings. We utilize state-of-the-art instrumentation including advanced ion chromatography systems capable of detecting trace levels of anions down to parts per billion (ppb) concentrations.
The testing not only helps in maintaining the quality of water supplies but also aids in understanding potential sources of contamination which could impact public health significantly. By offering this service, we contribute towards safeguarding human health and environmental sustainability.

Scope and Methodology
The scope of ISO 10304 ion chromatography testing is broad, encompassing the analysis of multiple anion species in water samples. The methodology involves meticulous sample preparation followed by separation using high-performance liquid chromatography (HPLC) equipped with appropriate detectors.
Sample collection follows strict protocols ensuring representative sampling across different water bodies and sources. Once collected, samples undergo rigorous filtration to remove particulates that may affect the chromatographic process. After filtration, dilution steps are implemented if required, based on initial concentration estimates.
The heart of the methodology lies in the use of ion chromatography where the sample is introduced into a column packed with anion-exchange resin. The separation occurs as mobile phase elutes through the column carrying individual anions at distinct retention times characteristic to their chemical properties.
At specific intervals, the separated ions are detected using either UV-Vis or conductivity detectors depending on the nature of the targeted analytes. Detection sensitivity is crucial here; it allows for accurate quantification even at very low concentrations.
The entire procedure ensures that results obtained reflect true concentrations of anions in water samples. This precision is vital not only for compliance with regulatory standards but also for scientific research aimed at improving water quality and identifying potential contaminants early.
