<p>This document specifies the fundamental structure and the most important performance characteristics of automated measuring systems for carbon monoxide (CO), carbon dioxide (CO<sub>2</sub>) and oxygen (O<sub>2</sub>) to be used on stationary source emissions. This document describes methods and equipment for the measurement of concentrations of these gases.</p>
<p>The method allows continuous monitoring with permanently installed measuring systems of CO, CO<sub>2</sub> and O<sub>2</sub> emissions. This international standard describes extractive systems and in situ (non-extractive) systems in connection with analysers that operate using, for example, the following principles:</p>
<p>— infrared absorption (CO and CO<sub>2</sub>);</p>
<p>— paramagnetism (O<sub>2</sub>);</p>
<p>— zirconium oxide (O<sub>2</sub>);</p>
<p>— electrochemical cell (O<sub>2</sub>);</p>
<p>— tuneable laser spectroscopy (TLS) (CO, CO<sub>2</sub> and O<sub>2</sub>).</p>
<p>Other instrumental methods can be used provided they meet the minimum requirements proposed in this document.</p>
<p>Automated measuring systems (AMS) based on the principles above have been used successfully in this application for measuring ranges which are described in Annex G.</p>
