Description

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 furnacetemperatures.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.
Up to five temperature steps (“ramps”) can be programmed for each application. The temperature levels and their durations are selectable. The maximum temperature is 1000°C.
Depending on the application step, either O2can be used as furnace atmosphere (oxidation of the sample) or inert gas like N2or argon.
The detection system of ELTRA’s CW-800M is very sensitive, reliable and guarantees a long lifetime. It can be customized according to the user’s requirements. Two infrared cells can be combined independently and allow highly precise measurement of the released CO2and H2O.

Application Examples

cement, gypsum, limestone, minerals, ores, slag, soil, waste
