Abstract: | 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). |
