Full title and description

STB PD ISO TS 17379-1-2013 — Water quality — Determination of selenium — Part 1: Method using hydride generation atomic fluorescence spectrometry (HG‑AFS). This Technical Specification describes a trace analytical procedure for measuring inorganic selenium in aqueous matrices using hydride generation coupled to atomic fluorescence detection, intended for routine monitoring and laboratory analysis of drinking, surface, ground and rain waters.

Abstract

ISO/TS 17379-1:2013 specifies a hydride generation — atomic fluorescence spectrometry (HG‑AFS) method for the determination of selenium in waters. The method is applicable to drinking water, surface water, ground water and rain water, with an application range typically from 0.02 µg/L up to 100 µg/L (higher concentrations may be handled by dilution). The procedure focuses on inorganic selenium species; it is unlikely to detect organoselenium compounds and sensitivity depends on operating conditions and sample preparation (including pre‑reduction steps and the use of high‑purity reagents).

Scope

This Technical Specification provides a validated analytical procedure for determining selenium concentrations in aqueous environmental and potable water samples using hydride generation atomic fluorescence spectrometry (HG‑AFS). It covers required reagents and standards, apparatus and instrumental set‑up, sampling and sample preparation (including pre‑reduction), procedure and calibration, expression of results and reporting, and informative annexes with performance data and figures. The method is aimed at inorganic selenium species and is not intended to reliably quantify organoselenium compounds. Typical operational range is about 0.02 µg/L to 100 µg/L, with sample dilution recommended for higher concentrations.

Key topics and requirements

• Analytical technique: hydride generation coupled with atomic fluorescence spectrometry (HG‑AFS).
• Target analyte: selenium (primarily inorganic forms); limited detection of organoselenium species.
• Applicable matrices: drinking water, surface water, ground water and rain water.
• Quantitative range: approximately 0.02 µg/L to 100 µg/L (instrument‑ and condition‑dependent).
• Sample handling: sampling guidance, pre‑reduction steps, and avoidance of contamination using high‑purity reagents.
• Quality assurance: calibration procedures, performance checks, expression of results, and test report content.
• Interferences and limitations: discussion of potential interferences, effects on sensitivity, and recommended mitigation.
• Informative annexes: figures, additional information and performance data to support method validation and implementation.

Typical use and users

Used by environmental and analytical testing laboratories, water utilities, regulatory agencies, research institutions and consultants performing routine and compliance monitoring of selenium in natural and drinking waters. Instrument manufacturers, method developers and quality managers may also use the specification when validating or implementing HG‑AFS methods for selenium determination.

Related standards

ISO/TS 17379‑1 is part of a small series for selenium determination; a companion document is ISO/TS 17379‑2:2013 (hydride generation atomic absorption spectrometry, HG‑AAS). The specification cross‑references common sampling and laboratory practice standards such as the ISO 5667 series (water sampling), ISO 3696 (water for analytical laboratory use) and other ISO methods and test reporting guidance (for example ISO 8466‑1 and relevant analytical‑chemistry standards). National adoptions and publisher‑specific publications (e.g., BSI national documents) may exist.

FAQ

Q: What is this standard?

A: ISO/TS 17379‑1:2013 is a Technical Specification from ISO that defines a hydride generation — atomic fluorescence spectrometry (HG‑AFS) method for determining selenium in various water matrices.

Q: What does it cover?

A: It covers the analytical principle, required reagents and apparatus, sampling and sample preparation (including pre‑reduction), instrumental set‑up, calibration, calculation and expression of results, reporting requirements, and informative annexes with figures and performance data. The method is aimed at inorganic selenium and gives a practical application range (approx. 0.02 µg/L to 100 µg/L).

Q: Who typically uses it?

A: Environmental and water‑testing laboratories, water utilities, regulators, researchers and consultants who perform trace selenium analyses in drinking, surface, ground and rain waters; also useful for instrument vendors and method validators.

Q: Is it current or superseded?

A: The document was published in 2013 (Edition 1) and is a Technical Specification. ISO records show the document was last systematically reviewed and confirmed on 4 August 2023, so the 2013 edition remains current as of that review date. Users should check with their national body or ISO for any subsequent revisions or replacements before applying the method for regulatory compliance.

Q: Is it part of a series?

A: Yes — it is part of the ISO/TS 17379 series for determination of selenium. A closely related part is ISO/TS 17379‑2:2013 which specifies a hydride generation — atomic absorption spectrometry (HG‑AAS) method; both parts address selenium determination in water using different detection techniques.

Q: What are the key keywords?

A: Selenium; HG‑AFS; hydride generation; water quality; trace analysis; detection limit; sampling; pre‑reduction; calibration; environmental monitoring.
