The elemental analyzer ELEMENTRAC CS-i measures the carbon and sulfur concentration in predominantly inorganic samples through combustion in an induction furnace and the subsequent analysis of the gaseous combustion products carbon dioxide and sulfur dioxide.
ELTRA's ELEMENTRAC CS-d is the only analyzer in the market for determination of carbon and sulfur in organic as well as inorganic samples. For this purpose, the ELEMENTRAC CS-d is equipped with both an induction and a resistance furnace (ELTRA Dual Furnace Technology), covering the full range of carbon and sulfur analysis.
The ELEMENTRAC CS-r analyzer determines the elements carbon and sulfur by combustion of the sample in an oxygen stream and subsequent measurement of the combustion gases CO2, SO2 and H2O in selective infrared measuring cells. A high sample weight of up to 500 mg ensures excellent reproducibility of the elemental analysis results, even for heterogeneous samples.

ELTRA’s 580A analyzers (A = Autoloader) are equipped with an automatic sample loader, allowing for analysis of large numbers of samples without operator intervention. The sample loader is available in two versions to accommodate 36 or 130 crucibles. The CS-580A is based on the technology of the CS-580 analyzer and features a vertical resistance furnace with ceramic tube.

Determination of released carbon dioxide and water is a special requirement for quality control in the cement and lime industry. ELTRA’s CW-800 analyzer is designed for the precise, simultaneous determination of carbon dioxide and water in lime, gypsum and cement from trace level up to 100 % (depending on sample weight). Other sample materials include ores, soil and minerals. The CW-800 is equipped with a resistance furnace with quartz tube for sample oxidation and can provide temperatures up to 1000 °C. The temperature of the CW-800 can be set up in steps of 1 °C and the temperature is fixed during measurement. As common carrier gas in the CW-800 nitrogen is used.
ELTRA’s CW-800M analyzer is designed for fractional analysis of carbon and water in one single operation. It is based on the proven technology of the CW-800 but has a modified furnace which allows fast adjustment of the temperature in the furnace. Different fractions of carbon and water of the sample are analyzed by applying different furnace temperatures. ELTRA’s CW-800M analyzer is designed for the precise, simultaneous determination of carbon (released as CO2) and water in lime, gypsum and cement from trace level up to 100 % (depending on sample weight). Other sample materials include ores, soil, minerals, slags and waste.
Determination of surface carbon is a special requirement for quality control in the metal producing and metal working industry. ELTRA’s SurfaceC-800 analyzer is designed for the precise determination of surface carbon in numerous kinds of solid samples from trace level up to 1000 µg/cm2. The SurfaceC-800 is equipped with a resistance furnace with quartz tube for sample oxidation and can provide temperatures up to 1000 °C. The temperature of the SurfaceC-800 can be set up in steps of 1 °C. As common carrier gas in the SurfaceC-800 oxygen is used.
