For Organic Samples by High Temperature Resistance Furnace
CSBox Tube CS Analyzer is used to determine Carbon and Sulfur in Organic samples like Coal, Coke, fuel oils, soil, Waste samples, Biomass and other Organic samples.
The analyzer provides simultaneous Carbon and Sulfur determination with minimal sample preparation. It consists of two independent IR cells with a wide measuring range of Carbon and Sulfur. The measuring range of each IR cell is modified to the user’s specific requirement to ensure optimum measurement conditions for each application.
CSBox Tube is supplied with a comprehensive software package which includes statistical reports, diagnostics features and other functions.
We can offer analytical balances which are compatible with our CSBox Tube series analyzers from world-renowned manufacturers. Please do contact us for further information.
We offer wide variety of certified reference materials with various ranges
We also offer a full range of consumables and accessories such as crucibles, boats, Combustion tube, glassware and other miscellaneous operating accessories.
CSBox Tube CS is computer-controlled instrument used for simultaneous determination of Carbon & Sulphur in a wide variety of Organic materials like coal, coke, oils, feed & biomass , cement, soils & more
The Analyzer employs high-temperature combustion followed by non-dispersive infrared detection. The sample is weighed (generally 100 mg) into a ceramic combustion boat and is then combusted in a pure oxygen environment where temperatures up to 1500 deg C are maintained.
During combustion the Carbon & Sulphur present in sample material forms Carbon Dioxide (CO2) & Sulfur Dioxide (SO2).The Unique design of the Analyzer prevents any atmospheric gases to enter combustion zone.
Sample + O2 Heat CO2 + SO2 + H2O
The CO2 & SO2 gases are selectively passed through glass tubes filled with Magnesium Perchlorate to trap moisture. The sample gases free of moisture are passed through two independent Non-Dispersive Infrared Detectors (NDIR) cells.
The Sulfur IR cell measures the concentration of SO2 gas & Carbon IR cell measures the concentration of CO2 gas. The analyzer converts these values to percentages/ppm concentration.
NDIR cells work on the principle that the CO2 & SO2 gases absorb Infrared(IR) energy at unique wavelengths of the IR spectrum.
