Thermal conductivity cell is the primary element of a/an _____________ analyser?
Correct answer: B. Carbon dioxide
- A. Oxygen
- B. Carbon dioxide
- C. Carbon monoxide
- D. Sulphur dioxide
Explanation
A thermal-conductivity cell detects changes in gas composition from the difference in thermal conductivity between the sample and a reference gas. Carbon dioxide analysers commonly use this principle, while oxygen analysers more typically use paramagnetic cells.
