The paper describes a dual-resolution Raman spectroscopy instrument for simultaneous measurements of N2, O2, CO, CO2, H2, H2O, C2H2, CH4, C2H4, C2H6, C2H6O in DME-air flames. Measurements in vertical flames are used to calibrate the instrument. Data collected in a laminar, premixed DME-air flame from a Tsuji burner are used to characterize the accuracy and the precision of the instrument.
