Eltra Carbon / Water Analyzer CW-800

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 a 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.

Advantages

• Simultaneous carbon dioxide and water determination with minimal sample preparation
• Rapid, precise, accurate, and reliable element determination
• A wide range of materials can be analyzed
• Resistance furnace temperature can be set up to 1000 °C in steps of 1° C
• Customized infrared cells provide a wide, dynamic measuring range
• Due to gold IR path, increased cell live time for analysis of halogen or acid-containing samples
• Powerful software (multilingual, customized display, the export of results)
• Single and multi-point calibration
• No halogen trap required
• Electronic gas flow control
• Low maintenance
• The robust design allows usage in production control and laboratory
