Which of the Following Can Be Used to Analyze Multiple

Question

Which of the following can be used to analyze multiple gases simultaneously?
A) Gas chromatograph
B) Polarographic electrode
C) Zirconium fuel cell
D) Paramagnetic sensor

Accepted Answer

Gas chromatographs are able to analyze multiple gases simultaneously through the use of multiple columns, each designed to separate a specific gas. Polarographic electrodes and zirconium fuel cells are used for measuring single gas concentrations, while paramagnetic sensors are limited to a specific set of gases that exhibit magnetic properties.
