ABSTRACT OF THE DISCLOSURE An improved flame photometry detector to give direct quantitative detection of molecules containing sulfur by: - the total combustion of the mixture to be analyzed so as to transform the sulfur into sulfur oxide (primarily SO2); - the linearization, by an electronic device, of the signal supplied by the electrometer, in series with the photo- multiplier of the detector, prior to recording (this results in the proportionality of the recording to the number of sulfur- containing molecules detected); and preferably the provision of a leakage flow beyond the burner and in front of the detection so as to avoid saturation of the detector. These improvements can be applied to the analysis of a hydrocarbon mixture and of sulfur compounds which have been previously eluted on a chromatographic column.
