  • System for determining total sulfur content
    Patent number: 7141211
    Abstract: In order to determine the total sulfur content of a sample (1), the sample is uniformly combusted with a flame (8). The combustion product sulfur dioxide is fed to a gas chromatograph (15) in which it is separated from other combustion products (9) and is then fed to a detector (17), which is situated downstream and which is provided for determining sulfur dioxide concentration. The combustion of the sample (1) is preferably effected in a flame ionization detector (19), with whose measurement signal (21) the detector signal (20) generated by the detector (17) is freed from signal contents based on non-uniformities of the combustion process.
