Oxidation of sulfur components to SO2


The GasOxidizer is a software-controlled tube furnace that enables the oxidation of exhaust gases from combustion engines. The GasOxidizer was developed to provide a rapid and time-resolved on-line measurement technology for the oil consumption of combustion engines.

A compound contained in the oil (sulfur) is used for the analysis. This tracer component is part of a chemical transformation in the fuel chamber. It is determined in the exhaust gas and then correlated to the consumed oil. With the SO tracer method, the sulfur component is determined by measuring sulfur dioxide (SO2) in the exhaust gas.

With the GasOxidizer you have shorter measuring times and the possibility to measure the low oil consumption of modern engines. The V&F GasOxidizer is used to ensure that all sulfur components in the exhaust gas can be measured as SO2. With this instrument, all sulfur components are oxidized to SO2 by adding oxygen O2 , which is converted to ozone O3. For the quantitative determination of SO2 in automotive exhaust gases, the proven and tested Ion Molecular Reaction (IMR-MS) mass spectrometry is applied.
