ABSTRACT:
System and method for temperature resolved molecular emission spectroscopy of solid, liquid or gaseous materials are described wherein a sample is vaporized and decomposed, and the vaporous sample is transported into a combustion flame; a spectrum of intensity of the optical emission from the flame at a selected wavelength versus temperature of the sample define molecular peaks which are characteristic of the sample material and allows both qualitative and quantitative analysis of the sample.
