Gas analysis is commonly done using the___________________?
Correct answer: A. Thermal conductivity cell
- A. Thermal conductivity cell
- B. X-ray diffraction
- C. Mass spectrometer
- D. Emission spectrometer
Explanation
A thermal conductivity cell compares the thermal conductivity of a gas sample with a reference gas, making it useful for continuous gas composition analysis. Mass spectrometers are more sophisticated and selective, but are not the usual answer for routine gas analysis.
