Comprehensive Guide to ISO 18664 Quantitative Analysis of Nitrate in Leafy Vegetables Laboratory Testing Service Provided by Eurolab

ISO 18664 is an international standard developed by the International Organization for Standardization (ISO) that provides a method for the quantitative analysis of nitrate in leafy vegetables. This standard is intended to ensure the accuracy and reliability of laboratory testing results, thereby protecting consumers from potential health risks associated with high levels of nitrates in food products.

Legal and Regulatory Framework

The European Union has implemented several regulations and directives related to food safety and quality, including Regulation (EC) No 1881/2006, which sets maximum limits for nitrate content in certain foodstuffs. In addition, the EUs General Food Law Regulation (EC) No 178/2002 establishes a framework for ensuring the safety of food products, including the requirement for testing and analysis.

International and National Standards

ISO 18664 is based on the principles outlined in ISO 5725-1:1994, which provides general requirements for laboratory measurement and test results. Other relevant standards include:

  • EN 15763:2010 (European Standard) - Nitrate determination by ion chromatography

  • TSE 1487 (Turkish Standard) - Determination of nitrate in leafy vegetables by ion chromatography

  • ASTM E1619-16 (American Standard) - Standard Test Method for Determining the Nitrate Content of Leafy Vegetables

    • Standard Development Organizations

    ISO is a non-profit organization that develops and publishes international standards through a consensus-driven process involving representatives from member countries. Other standard development organizations relevant to this testing service include:

  • International Electrotechnical Commission (IEC)

  • American Society for Testing and Materials (ASTM)

  • Deutsches Institut für Normung (DIN)

    • Standard Evolution and Updates

    Standards are subject to revision as new technologies, methods, or research become available. The development of ISO 18664 involved extensive collaboration among experts from around the world, ensuring that the final standard is both comprehensive and practical.

    Standard Numbers and Scope

    The following standards relate to the testing service provided by Eurolab:

  • ISO 18664: Quantitative analysis of nitrate in leafy vegetables - Ion chromatography method

  • EN 15763:2010 (European Standard): Nitrate determination by ion chromatography

    • Industry-Specific Standards Compliance Requirements

    Compliance with relevant industry-specific standards is mandatory for food manufacturers, processors, and distributors. Failure to comply can result in severe penalties, including product recalls, fines, and reputational damage.

    ISO 18664 Quantitative Analysis of Nitrate in Leafy Vegetables testing involves the following steps:

    1. Sample Preparation: Collect and prepare leafy vegetable samples for analysis.

    2. Ion Chromatography: Use ion chromatography to separate and quantify nitrate ions.

    3. Measurement and Analysis: Measure and analyze the resulting chromatograms to calculate nitrate levels.

    Ion Chromatography Method

    The ion chromatography method involves the following steps:

    1. Sample Injection: Inject the prepared sample into the ion chromatograph.

    2. Column Separation: Separate the nitrate ions from other components in the sample using a column packed with an ion-exchange resin.

    3. Detector Response: Measure the detector response to determine the concentration of nitrate ions.

    Measurement and Analysis

    The resulting chromatograms are analyzed using specialized software to calculate nitrate levels. This information is used to evaluate the safety and quality of leafy vegetable products.
