It works on the principle of dynamometer i.e. To reduce interferences from instrument drift, reference measurements of pure carrier gas are made prior to each analysis.An electrodynamometer or simply Dynamometer wattmeter is an instrument that is universally used for the measurement of DC as well as AC electric power. The concentration of unknown samples is determined relative to calibration standards. Incident IR energy at these wavelengths is absorbed as the gases pass through IR absorption cells. Non-dispersive infrared cells are based on the principle that CO 2 and SO 2 absorb infrared (IR) energy at unique wavelengths within the IR spectrum. The final component in the flow stream is an electronic flow sensor, which is used for diagnostic purposes to monitor the carrier flow. A pressure controller is used to maintain constant pressure in the NDIR cells so as to reduce interference from natural variations in atmospheric pressure. Carbon is then detected as CO 2 by another NDIR cell. The gas flow continues past a heated catalyst, where carbon monoxide (CO) is converted to CO 2 and where SO 2 is converted to sulfur trioxide (SO 3), which is subsequently removed by a filter. Carbon and sulfur present in the sample are oxidized to carbon dioxide (CO 2) and sulfur dioxide (SO 2), and swept by the oxygen carrier through a drying reagent and then through a non-dispersive infrared (NDIR) cell, where sulfur is detected as SO 2. The instrument features custom software designed specifically for touch operation.Ī pre-weighed sample of approximately 1 gram is combusted in a stream of oxygen using RF induction to heat the sample. The CS744 carbon/sulfur analyzer is designed for wide-range measurement of carbon and sulfur content of metals, ores, ceramics, and other inorganic materials. Optimized emitter control and detection circuitry improves IR cell lifetime and long-term stability.Temperature stabilized construction provides increased protection from ambient temperature fluctuations.High-velocity vacuum system keeps dust and debris contained. Optional 10-and 60-sample autoloaders available for hours of worry-free operation.18 MHz, 2.2 kW induction furnace for rapid and consistent combustion.Integrated oxygen lance floods crucible with high-purity oxygen to promote complete combustion.
