Hydrogen Chloride and Hydrogen Fluoride are among the most important pollutants monitored from waste incineration plants, cement kilns and power plants co-incinerating waste. Due to the reactive nature of these gases and their low Emission Limit Value (ELV), measuring these gases with the required low level of uncertainty has been a challenge. New standards for instrumental methods of HCl measurement and manual determination of HF are due to be published by CEN TC264/WG3 in the near future. This talk gives an overview of the current status of test methods and currently available instrumental measurement techniques.
