Carbon hydrogen analyzerIt is a professional instrument used for precise determination of carbon and hydrogen content in coal and other organic matter. Its core principle is based on high-temperature combustion method, combined with Coulomb analysis and weight method to achieve data automation processing. It is widely used in coal, chemical, metallurgical, power and geological exploration fields.
The hydrocarbon analyzer converts carbon and hydrogen elements in the sample into carbon dioxide and water through high-temperature combustion method, and then uses different technical methods for quantitative analysis:
Combustion conversion: The sample burns in an oxygen stream, and the generated water and carbon dioxide are captured by water absorbing agents (such as anhydrous magnesium perchlorate) and carbon dioxide absorbing agents (such as alkali asbestos), respectively.
Quantitative analysis:
Coulombic analysis method: By measuring the amount of electricity consumed during the electrolysis process, the hydrogen content can be directly calculated (suitable for precise determination of hydrogen).
Weight method: By weighing the absorbent to increase weight, calculate the carbon content (suitable for stable measurement of carbon).
Data processing: Combined with a microcomputer system, achieve automatic data processing, result output, and storage, with a single testing time of about 10-15 minutes.
