EN 1233:1996 - Overview

Standard: EN 1233:1996 (CEN)

This European Standard specifies two atomic absorption spectrometric methods for the determination of chromium in water. It is intended for laboratories and practitioners engaged in water quality analysis who require validated procedures for accurate chromium measurement. The document covers two separate sections: Method A - flame atomic absorption spectrometry (flame AAS) and Method B - electrothermal atomization atomic absorption spectrometry (electrothermal AAS).

Key Topics

The standard focuses on practical analytical approaches without prescribing instrument-specific hardware. Key topics include:

• Two complementary AAS methods: flame AAS for routine determinations and electrothermal AAS for enhanced sensitivity where required.
• Scope and applicability: determination of chromium in various water matrices where atomic absorption spectrometry is appropriate.
• Laboratory relevance: guidance to support consistent analytical practice across environmental and public health laboratories.

Keywords: chromium, atomic absorption spectrometry, AAS, flame AAS, electrothermal AAS, water quality, environmental monitoring

Applications

EN 1233:1996 is applicable in contexts where reliable measurement of chromium concentrations in water is necessary for public health, environmental protection, and regulatory compliance. Typical applications include:

• Drinking water monitoring to ensure potability and public safety.
• Environmental surveillance of surface waters, groundwater and monitoring programs.
• Wastewater and industrial discharge testing to assess treatment performance and compliance with permits.
• Laboratory quality assurance, providing methods that assist in method selection based on sensitivity and matrix considerations.

Benefits of using the standard methods:

• Consistent, comparable results across different laboratories and monitoring programs.
• Method choice flexibility, allowing selection of flame or electrothermal AAS depending on required detection limits and sample characteristics.
• Support for regulatory and compliance activities through standardized analytical approaches.

Related Standards

EN 1233:1996 is part of a broader framework of water quality and analytical standards. For comprehensive laboratory practice, this standard is typically used in conjunction with:

• Other CEN and international standards covering sampling, sample preservation and quality assurance.
• Laboratory quality management and accreditation guidelines that ensure traceability and method validation.

For users implementing EN 1233:1996, it is recommended to align method selection with the monitoring objective, required sensitivity, and laboratory capabilities. The standard provides a practical foundation for accurate chromium determination using atomic absorption spectrometric techniques.
