Oxygen & Nitrogen & Hydrogen Analyzer

A graphite crucible is placed on the holder and the impulse furnace is closed by the pneumatic system.The sample of typically 1g is dropped into the loading mechanism after weighing. The outgassing phase starts the analysis cycle to clean the furnace from Oxygen and Nitrogen out of the air.The sample loading mechanism release the sample into the now cleaned crucible.The oxygen content of the sample react with the Carbon from the graphite crucible to CO and the Nitrogen content to elemental N2 gas at temperatures of about 2200°C. Both gases were transported by the Helium carrier gas to the oxidation furnace where Copper Oxide converts the CO to CO2. This CO2 concentration is analysed by an infrared absorption detector and the Oxygen concentration is calculated.The Nitrogen is analysed afterwards by a thermal conductivity detector.

Carbon & Sulfur Analyzer


A sample of typically 0.5 to 1.0g is weight into a crucible together with 1.5g of tungsten accelerator. This crucible is placed on a pedestal which drives it into an induction furnace by a pneumatic system. The sample is completely burned in the furnace by pure Oxygen.The Carbon of this sample is oxidized to CO2 and the Sulphur content to SO2. Dust and other particles are trapped in a filter system.The CO2 and SO2 is transported from the furnace in the Oxygen carrier gas to the infrared adsorption detectors.The actual gas concentrations are determined and the data are send to the PC.The operation software is calculating the results after integration of the whole signal peaks. A calibration with known samples builds up a database which created the necessary accuracy and precision. The burned crucible is driven out of the furnace by the pneumatic system and disposed by an operator. The furnace and gas flow system is purged after analysis by clean Oxygen to avoid any interference (memory effect) of the individual samples.
