Towards a TDLAS based optical gas standard for the absolute HCl measurements in flue gases from combustion process

We present our new dTDLAS based HCl spectrometer, specially designed and optimized to measure traceable HCl concentration in different matrices (high temperature, high water vapor and CO2 contents) motivated by large-scale power stations or biomass burning domestic boilers. This system is designed to serve as an optical gas standard (OGS) and thus as a traceable transfer standard to directly quantify HCl emissions or calibrate HCl sensors or dynamically generated gas standards in the field. It employs a mid-infrared interband cascade laser (ICL) and is targeting the HCl transition lines in the fundamental band to achieve less 1 ppm (at 1 meter) sensitivity and meet the compatibility goal set by lowered HCl ELVs in the European legislation such as the Industrial Emissions Directive (IED).
