Current methods for determining the composition of coal gasification streams generally involve sampling, some treatment, and inherent delay times prior to analysis. Optical instrumentation, on the other hand, provides the potential for on-line, rapid-response monitoring of gasifier streams. Among the optical technques that appear quite promising for this application are coherent anti-Stokes Raman scattering (CARS), laser-induced breakdown spectroscopy (LIBS), Fourier transform infrared spectroscopy (FTIR), laser-induced fluorescence (LIF), and synchronous detection of laser-induced fluorescence (SDLIF).
