Full title and description

ISO 10304-1:2007 — Water quality — Determination of dissolved anions by liquid chromatography of ions — Part 1: Determination of bromide, chloride, fluoride, nitrate, nitrite, phosphate and sulfate. This standard specifies an ion‑chromatographic method (typically using a low‑capacity anion exchanger with conductivity detection, optionally with a suppressor or UV detector) for quantifying common dissolved anions in a wide range of water matrices.

Abstract

ISO 10304-1:2007 specifies a method for the determination of dissolved bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate in water (including drinking water, ground water, surface water, waste water, leachates and marine water) by liquid chromatography of ions. Typical detection is by conductivity (with optional suppression) and, for some analytes, UV detection; the standard gives practical lower limits of application and notes how pre‑treatment or pre‑concentration can extend the working range.

Scope

The standard applies to the quantitative determination of the specified dissolved anions in aqueous samples using ion‑exchange liquid chromatography with appropriate detection. It covers typical sample matrices such as drinking water, ground water, surface water, waste water, leachates and marine water, and gives lower limits of application for each anion as well as notes on sample pre‑treatment, interferences and methods to extend sensitivity (e.g., pre‑concentration, UV detection).

Key topics and requirements

• Target analytes: bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate.
• Separation: liquid chromatography of ions using a low‑capacity anion exchanger.
• Detection: conductivity detection (commonly with a suppressor); UV detection noted for certain analytes to improve sensitivity.
• Performance limits: specified lower limits of application (example: ≥0.05 mg/L for bromide and nitrite; ≥0.1 mg/L for chloride, fluoride, nitrate, orthophosphate and sulfate), with guidance on extending the working range.
• Sample types and pre‑treatment: practical guidance on matrix effects, required pre‑treatment and pre‑concentration techniques where applicable.
• Quality aspects: calibration, method validation/verification, interference checks and precision considerations appropriate for routine and regulatory testing.

These topics and requirements are summarized from the ISO standard text and its corrigendum.

Typical use and users

Laboratories performing environmental and drinking‑water analysis (municipal, regulatory and private contract labs), wastewater and industrial monitoring laboratories, research institutions studying water chemistry, and water utilities that require routine monitoring of anionic composition. The method is used where reliable quantification of common anions is required for compliance, process control, or research.

FAQ

Q: What is this standard?

A: ISO 10304-1:2007 is an international standard that specifies an ion‑chromatographic method for determining dissolved anions (bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate) in water.

Q: What does it cover?

A: It covers the analytical procedure (separation and detection), recommended detection techniques (conductivity with optional suppression; UV where relevant), lower limits of application, sample pre‑treatment guidance, interference considerations and quality/validation aspects for a range of water matrices.

Q: Who typically uses it?

A: Environmental and public‑health laboratories, water utilities, industrial monitoring labs, contract testing laboratories and researchers who need standardized, validated methods for measuring common anions in water.

Q: Is it current or superseded?

A: ISO 10304-1:2007 is the 2007 (second) edition and the ISO record shows it as published and later modified by a technical corrigendum in 2010; the ISO entry indicates the publication was reviewed and confirmed in ISO’s review process (confirmed in 2021), so this edition remains the current version unless a newer revision is issued by ISO.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 10304 series (other parts and earlier editions exist; some earlier parts/editions have been withdrawn and replaced by the 2007 edition). The 2007 edition is accompanied by a technical corrigendum published in 2010.

Q: What are the key keywords?

A: Anions; ion chromatography; liquid chromatography of ions; conductivity detection; suppressor; bromide; chloride; fluoride; nitrate; nitrite; phosphate; sulfate; water quality; ISO 10304-1.
