WebA TDLAS based system for simultaneous measurements of C 2 H 4 concentration and temperature is achieved with the help of the differential absorption scheme which can eliminate the inferences from other species. The measurements are performed with C 2 H 4 /N 2 mixture of different concentrations in a static cell from 300 to 900 K at normal ... WebJun 10, 2016 · From the 14′645 TDLAS measurements obtained, 2′460 data points (16.8%) were omitted due to non-normal distribution of the data series, hindering the use of the 4σ approach.
