The procedures to determine the performance characteristics are also specified. Furthermore, it describes methods and equipment to determine NH <sub>3<\/sub> in flue gases including the sampling system and sample gas conditioning system.<\/p>\n<p>This International Standard describes extractive systems, based on direct and indirect measurement methods, and <i>in situ<\/i> systems, based on direct measurement methods, in connection with a range of analysers that operate using, for example, the following principles:<\/p>\n<ul>\n<li>\n<p>ammonia conversion to, or reaction with NO, followed by chemiluminescence (CL) NO <sub>x<\/sub> difference measurement for ammonia (differential NO <sub>x<\/sub>);<\/p>\n<\/li>\n<li>\n<p>ammonia conversion to, or reaction with NO, followed by non-dispersive ultraviolet (NDUV) spectroscopy NO <sub>x<\/sub> difference measurement for ammonia (differential NO <sub>x<\/sub>);<\/p>\n<\/li>\n<li>\n<p>Fourier transform infrared (FTIR) spectroscopy;<\/p>\n<\/li>\n<li>\n<p>non-dispersive infrared (NDIR) spectroscopy with gas filter correlation (GFC);<\/p>\n<\/li>\n<li>\n<p>tuneable laser spectroscopy (TLS).<\/p>\n<\/li>\n<\/ul>\n<p>The method allows continuous monitoring with permanently installed measuring systems of NH <sub>3<\/sub> emissions, and is applicable to measurements of NH <sub>3<\/sub> in dry or wet flue gases, for process monitoring, long term monitoring of the performance of deNO <sub>x<\/sub> systems and\/or emission monitoring.<\/p>\n<p>Other equivalent instrumental methods can be used, provided they meet the minimum requirements proposed in this International Standard. The measuring system can be calibrated with certified gases, in accordance with this International Standard, or comparable methods.<\/p>\n<p>The differential NO <sub>x<\/sub> technique using CL has been successfully tested on some power plants where the NO <sub>x<\/sub> concentration and NH <sub>3<\/sub> concentration in flue gas after deNO <sub>x<\/sub> systems are up to 50&nbsp;mg (NO)\/m <sup>3<\/sup> and 10&nbsp;mg (NH <sub>3<\/sub>)\/m <sup>3<\/sup>, respectively.
