Comprehensive Guide to EPA Method 413.1 Total Kjeldahl Nitrogen Measurement Laboratory Testing Service Provided by Eurolab

EPA Method 413.1 Total Kjeldahl Nitrogen Measurement testing is a widely accepted and standardized laboratory procedure for determining the total nitrogen content in various substances, including water, wastewater, and industrial effluents. This method is governed by several international and national standards that ensure accuracy, precision, and reliability.

Relevant Standards

  • ISO 5665:2012: Water quality - Determination of total nitrogen (nitrate and nitrite as N) - Kjeldahl method

  • ASTM D1426-14: Standard Test Methods for Nitrogen in Water

  • EN ISO 5665:2007: Water quality - Determination of total nitrogen (nitrate and nitrite as N) - Kjeldahl method

  • TSE 6271: Turkish Standard for Water Quality - Determination of Total Nitrogen

    • These standards are developed and maintained by organizations such as the International Organization for Standardization (ISO), American Society for Testing and Materials (ASTM), and European Committee for Standardization (CEN). The development process involves a thorough review of the latest scientific research, expert opinions, and practical experience to ensure that the standard remains relevant, accurate, and reliable.
