Thermal conductivity measurement com-prises the working principle of a_________________?
Correct answer: B. CO2 analyser
- A. Polarimeter
- B. CO2 analyser
- C. Spectrometer
- D. Chromatograph
Explanation
A thermal-conductivity gas analyser infers composition from the change in heat conduction of the gas mixture, and it is commonly used for CO2 analysis. Polarimeters, spectrometers and chromatographs use different measurement principles.
