Acid gases: HF and HCl - what impact will new EN standards for these gases have?

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.
