Towards an Optical Gas Standard for Traceable Calibration-Free and Direct NO<sub>2</sub> Concentration Measurements

Towards an Optical Gas Standard for Traceable Calibration-Free and Direct NO<sub>2</sub> Concentration Measurements

We report a direct tunable diode laser absorption spectroscopy (dTDLAS) instrument developed for NO<sub>2</sub> concentration measurements without chemical pre-conversion, operated as an Optical Gas Standard (OGS). An OGS is a dTDLAS instrument that can deliver gas species amount fractio...
