ISO 4224:2000

Ambient air — Determination of carbon monoxide — Non-dispersive infrared spectrometric method

This International Standard specifies a non-dispersive infrared spectrometry method for the continuous analysis

and recording of the carbon monoxide (CO) content of the ambient air.

The method is applicable to the determination of carbon monoxide concentrations from 0,6 mg/m3 (0,5 ppm volume

fraction) to 115 mg/m3 (100 ppm volume fraction).

The method has a lower limit of detection of about 0,06 mg/m3 (0,05 ppm volume fraction) carbon monoxide in air.
