This method is for the determination of carbon dioxide in workplace air. The sample is collected as an integrated sample in a Tedlar bag or other acceptable gas sampling bag. The sample is analyzed by GC/TCD (thermal conductivity detector). The working range of the method is 500 to 15,000 ppm.
NOTE: This is method S249 in a revised format.
