Eltra Carbon / Water Analyzer CW-800M

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 that 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. Up to five temperature steps (“ramps”) can be programmed for each application. The temperature levels and their duration are selectable. The maximum temperature is 1000°C. Depending on the application step, either O2 can be used as a furnace atmosphere (oxidation of the sample) or an inert gas like N2 or argon.

Eltra Carbon / Water Analyzer CW-800M | Descriptions

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 CO2 and H2O.

Advantages

• Simultaneous carbon dioxide and water determination with minimal sample preparation
• Analysis of TOC (total organic carbon) and tic (total inorganic carbon) without adding acids
• 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
• Up to 5 programmable steps with different temperatures ("ramps") can be defined
• 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
