A method and apparatus for making a quantitative determination of gaseous sulfur. The sulfur is illuminated with light having one or more spectral lines selected from a first group of peaks including positive peaks at wavelengths in nm of 263, 265.5, 268, 270.5, 273, 276, 279 and 282, and from a second group of peaks including negative peaks at wavelengths in nm of 264.5, 267, 269.5, 272, 275, 278 and 281. The absorption by the sulfur of the illuminating light is measured and this absorption is analyzed to determined sulfur content.
