Abstract BS EN ISO 13395:1996 is a European standard that specifies a method for the determination of nitrite nitrogen (NO2-N) and nitrate nitrogen (NO3-N) concentrations in water samples. The standard outlines a procedure that utilizes Continuous Flow Analysis (CFA) and Flow Injection Analysis (FIA) techniques with spectrometric detection. This method allows for the simultaneous measurement of both nitrite and nitrate nitrogen, as well as the determination of their sum. Here's a brief overview of the key aspects covered by this standard: The standard is focused on the analysis of nitrite and nitrate nitrogen in water samples. It provides guidance on the determination of these two parameters, which are important for assessing water quality, especially in environmental and industrial contexts. Applicability: This method is applicable to various types of water samples, including surface water, ground water, and wastewater. It is particularly useful for monitoring water quality and ensuring compliance with regulatory requirements. Continuous Flow Analysis (CFA): CFA is a technique used for automated chemical analysis. It involves the continuous flow of sample and reagents through a system of tubing and valves, allowing for efficient and rapid analysis. In this standard, CFA is employed for the determination of nitrite and nitrate nitrogen. Flow Injection Analysis (FIA): FIA is a subset of CFA and is often used for the analysis of specific chemical species within a sample. It involves injecting a discrete volume of sample into a flowing carrier stream of reagent, resulting in a rapid reaction and detection. FIA is utilized in this method to enhance the precision and efficiency of the analysis. Spectrometric Detection: Spectrometric detection refers to the use of a spectrophotometer or similar instrument to measure the absorbance or fluorescence of the sample after it has reacted with reagents. This allows for the quantification of nitrite and nitrate nitrogen concentrations based on their characteristic spectral properties. Sum of Nitrite and Nitrate Nitrogen: The standard provides guidance on how to determine the sum of nitrite and nitrate nitrogen concentrations in a water sample. This is often important for regulatory compliance and assessing overall nitrogen levels in water. Calibration and Quality Control: The standard also covers the calibration of the analysis system and the use of quality control procedures to ensure the accuracy and reliability of the results.
