You are asked to calibrate an O₂ analyzer. Which of the following gases would you use for this procedure?
1) 100% oxygen
2) 50% oxygen
3) 21% oxygen (room air)

Question

Quizplus · Accepted Answer

The O₂ analyzer is typically used to measure oxygen concentration in gases, so 100% oxygen would be the best choice for calibration. However, it is also important to calibrate the analyzer in room air, which contains 21% oxygen, to ensure accurate measurements in real-world conditions. Using 50% oxygen would not be necessary or helpful in this calibration procedure. Therefore, the best choice(s) would be 1 and 3 only (options A and C are incorrect).
