EN 14385 Mercury Emission Testing by Chromatography
The European standard EN 14385:2003 specifies the method for determining mercury emissions in flue gases from stationary combustion plants. This method employs gas chromatography to accurately measure trace amounts of mercury, ensuring compliance with environmental regulations and quality standards.
Mercury is a toxic heavy metal that poses significant risks to human health and the environment. Its presence in flue gases can lead to severe pollution if not controlled properly. The standard provides detailed guidelines on how to collect samples from combustion plants, prepare them for analysis, and conduct the chromatographic testing using specific instruments.
The method involves several key steps: first, sampling of flue gas at a representative location within the plant. Next, the sample is transported to the laboratory where it undergoes preliminary treatment if necessary. The actual measurement process uses thermal decomposition followed by absorption on activated carbon. This step converts mercury into volatile compounds which are then quantified using flameless atomic adsorption spectroscopy (FAAS).
The accuracy and precision of this technique make it suitable for both routine monitoring as well as research purposes. Compliance officers responsible for environmental protection will find this method particularly useful in ensuring that emissions meet specified thresholds set forth by regulatory bodies like the European Union.
For industries engaged in coal or biomass combustion, regular testing is essential to maintain compliance with emission limits prescribed under relevant directives such as Directive 2016/845/EU on the limitation of certain hazardous substances. By employing EN 14385 chromatography, these organizations can verify that their operations do not exceed permissible levels.
The standard also outlines quality assurance measures including validation procedures for equipment calibration and method performance checks. These steps ensure consistent results across different laboratories performing similar tests.
Additionally, EN 14385 provides recommendations regarding sample handling techniques aimed at minimizing contamination during transport from the source to the analytical facility. Properly trained personnel must follow these protocols rigorously to obtain reliable data indicative of actual emissions levels.
In summary, EN 14385 establishes a robust framework for quantifying mercury emissions through chromatographic analysis. Its application helps protect public health and supports sustainable industrial practices by facilitating accurate measurement and control over pollutants released into the atmosphere.
