Answer:D
Which of the following is the full scale range of Infrared spectroscopy method used for measurement of carbon monoxide?
A. 0-2 ppm B. 0-500 ppm C. 0-1 ppm D. 0-50 ppm
Explanation: The full scale range of Infrared spectroscopy method used for measurement of carbon monoxide is 0-50 ppm. It depends on the characteristic absorption of CO molecule at a particular wavelength.
