ppb Analysis At Its Best The continuously increasing requirements for environmental protection mean further decreasing threshold values for sulfur or nitrogen in fuels. Instruments for measuring these components have to correspond to these future requirements in their performance. Therefore, Elementar as the technology leader in elemental analysis, has developed the top level instrument for sulfur and nitrogen analysis which safely and accurately analyzes sulfur or nitrogen concentrations in mineral oils and other petrochemical products in the lower ppb range and exceeds the requirements of today’s standards by far. Automatic sample feeding The liquid autosampler VLS serves for precise, septum-free injection of up to 100 µl sample in just a few seconds injection time. Optionally, a solid sampler for up to 120 samples and modules for gas analysis and LPG can be provided. Full combustion The patented catalytic combustion at almost 1200°C allows 100% oxidation also for large sample amounts with short injection time and sharp peaks. Gas drying by means of the Permapure counterflow method follows directly after the combustion. Perfect gas control SO2 is collected on an adsorber tube acc. to the patented Elementar procedure and thermally released time delayed. This leads to a sharpening of the S peak and separation of interfering nitrogen oxides at the same time. Electronic mass flow controllers serve for stability of the measurement and of the calibration for months. Sensitive detection The applied detectors are CLD for NO and UV fluorescence for SO2 according to the ASTM standards. They are high performance instruments with an extreme sensitivity also for the upper measuring ranges up to 1000 ppm.
