Water analysis - Guidelines for the determination of total organic carbon (TOC) and dissolved organic carbon (DOC)

This European Standard gives guidance for the determination of organic carbon indrinking water, ground water, surface water, sea water and waste water. It dealswith definitions, interferences, reagents, and the sample pretreatment of water samples with a content of organic carbon ranging from 0,3 mg/l to 1000 mg/l while the lower value is only applicable in special cases, for example drinking water, measured with instruments capable of measuring these low levels.

Wasseranalytik - Anleitungen zur Bestimmung des gesamten organischen Kohlenstoffs (TOC) und des gelösten organischen Kohlenstoffs (DOC)

Diese Europäische Norm beschreibt eine Richtlinie zur Bestimmung von organischem Kohlenstoff in Trinkwasser, Grundwasser, Oberflächenwasser, Seewasser und Abwasser. Sie behandelt Festlegungen, Störungen, Reagenzien und die Probenvorbehandlung von Wasserproben mit einem Gehalt von 0,3 mg/l bis 1000 mg/l, wobei der untere Wert nur in besonderen Fällen, z.B. bei Trinkwasser erreicht werden kann, wenn mit Geräten gemessen wird, die eine Messung in derart niedrigen Bereichen erlauben.

Analyse de l'eau - Lignes directrices pour le dosage du carbone organique total (TOC) et carbone organique dissous (COD)

La présente Norme européenne est un guide pour la détermination de carbone organique dans l'eau potable, l'eau phréatique, l'eau de surface, l'eau de lacs et les eaux usées. Elle comprend les définitions, les interférences, les réactifs et le traitement préalable des échantillons d'eau dont la teneur en carbone organique s'élève de 0,3 à 1000 mg/l: la valeur inférieure ne pouvant être atteinte que dans les cas particuliers, par exemple, pour l'eau potable, lorsque l'on mesure à l'aide d'appareils permettant le dosage à faibles teneurs.

SIST EN 1484:1998 - Water analysis - Guidelines for the determination of total organic carbon (TOC) and dissolved organic carbon (DOC)

Overview

EN 1484:1997 (CEN) provides practical guidance for the determination of total organic carbon (TOC) and dissolved organic carbon (DOC) in a wide range of water matrices. The standard addresses drinking water, ground water, surface water, sea water and waste water. It focuses on definitions, potential interferences, recommended reagents and sample pretreatment for samples containing organic carbon between 0.3 mg/L and 1000 mg/L. The lower limit (0.3 mg/L) applies primarily in special cases such as drinking water and requires instruments capable of measuring low TOC/DOC levels.

Key Topics

  • Scope and applicability: Guidance for TOC and DOC determination across multiple water types.
  • Definitions: Clarifies terms used in TOC/DOC analysis to ensure consistent interpretation.
  • Interferences: Describes sources of analytical interference and considerations to minimise their impact.
  • Reagents: Outlines reagent use and handling principles relevant to organic carbon analysis.
  • Sample pretreatment: Guidance on preparing water samples to obtain representative and reliable measurements.
  • Measurement range: Practical considerations for analyzing concentrations from 0.3 mg/L up to 1000 mg/L, noting instrument requirements for low-level detection.

Applications

EN 1484:1997 is designed to support laboratories, water utilities and environmental monitoring bodies by promoting consistent TOC/DOC measurements and improving data comparability. Typical applications include:

  • Drinking water quality monitoring: Ensuring low-level organic carbon is reliably detected in treated water.
  • Environmental monitoring: Assessing organic carbon in rivers, lakes and marine environments.
  • Groundwater assessment: Supporting investigations of organic pollution and natural organic matter.
  • Waste water treatment monitoring: Tracking organic load and treatment performance.

Benefits of following the standard:

  • Improved reproducibility and comparability of TOC/DOC data across laboratories
  • Clear guidance on sample handling to reduce artefacts and interferences
  • Better selection and use of reagents and pretreatment steps for diverse water matrices

Related Standards

EN 1484:1997 should be used in conjunction with other water analysis and sampling standards and good laboratory practice documents. Related guidance typically covers:

  • Water sampling procedures and sample preservation
  • Instrument calibration and method validation for low-level organic carbon
  • National and international standards on water quality testing (EN, ISO and regional standards)

For laboratories and practitioners, EN 1484:1997 is a practical reference to harmonise TOC and DOC determinations and to support robust water quality programs across drinking, environmental and wastewater monitoring contexts.

The article discusses EN 1484:1997, a European standard that provides guidelines for determining the amount of organic carbon in various types of water. This includes drinking water, ground water, surface water, sea water, and waste water. The standard covers definitions, interferences, reagents, and the treatment of water samples containing organic carbon levels ranging from 0.3 mg/l to 1000 mg/l. However, the lower value is only relevant in specific cases, such as measuring organic carbon levels in drinking water using instruments capable of detecting low levels.
