Study Notes on Galvanic Fuel Cell Oxygen Analyzers
Galvanic Fuel Cell Oxygen Analyzer
Overview of Galvanic Fuel Cell Analyzer
Definition: A galvanic fuel cell analyzer creates electron flow as a result of the oxidation of oxygen.
Functionality: Produces a current that measures the partial pressure of oxygen in the surrounding environment.
Self-Powered: As a type of fuel cell, it generates its own electricity and operates independently of any external battery source.
Analyzing the Options for Correction
Option A
Statement: The galvanic fuel cell analyzer uses a battery.
Evaluation: Incorrect.
Explanation: The galvanic fuel cell does not have a battery; hence, this option is invalid.
Option B
Statement: If calibration fails, replace the fuel cell.
Evaluation: Correct.
Explanation: When calibration issues arise, the appropriate action is to change or replace the fuel cell to restore functionality.
Option C
Statement: Check the electrolyte level and refill if necessary.
Evaluation: Incorrect.
Explanation: The galvanic fuel cell does not use an electrolyte solution, making this response inappropriate for a galvanic fuel cell analyzer.
Note: This action would be relevant for a polarographic type analyzer which does use an electrolyte solution.
Option D
Statement: Utilize a mass spectrometer or infrared absorption analyzer at bedside.
Evaluation: Incorrect.
Explanation: Mass spectrometers and infrared absorption analyzers are primarily designed for laboratory environments and are not suitable for bedside usage in clinical settings.
Conclusion
Correct Answer: The most appropriate action for calibration failure in a galvanic fuel cell oxygen analyzer is to change or replace the fuel cell (Option B).
