Carbon Water Analyzer CW-800

Mã sản phẩm:

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. 

The detection system of ELTRA’s CW-800 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 CO2 and H2O.

Application Examples

Function Principle

Operation of the CW-800 analyzer is simple and convenient. The temperature of the CW-800 is set up to defined temperature up to 1000 °C. After weighing the sample in a quartz boat, it is placed on the loading mechanism of the furnace. In the following, the analysis can be started and the boat is introduced into the furnace by the user. Depending on the applied temperature, residual or crystallization water and CO2 (from CaCO3) is released from the sample and determined by the infrared cells. 

All data processing, control of the combustion process and calculating of the result is done by an external PC. The simultaneous determination of carbon dioxide and water only takes about 2 to 3 minutes.
