Quantitative analysis method for all form sulfur component of light carbon and its fractional distillation product

The utility model discloses a qualitative method and a quantitative method for analyzing various sulphur components of the light hydrocarbon and the fractionation products, wherein the qualitative method is to analyze the products with the adoptive gas phase mass spectrometer for obtaining the spectral configuration and then to determine the quality with the mode of combining the searching of standard atlas database and keeping time of the standard sulphur sample. The quantitative method is to use the gas chromatography combining cubic spline curves for determining the quantity. The utility model has the advantages that the establishment of the qualitative and the quantitative analysis methods for various sulphur components can provide necessary, accurate and effective data for utilizing the art of sulfur removal with light hydrocarbon fractional device and meanwhile can offer the foundation for determining the desulfurization catalyst for the device and guiding the production.
