1.1”This test method covers a rapid and simple field determination of carbon dioxide in natural gas pipelines. Available detector tubes provide a total measuring range of 100 ppm (parts per million) up to 60”’% by volume, although the majority of applications will be on the lower end of this range (that is, under 5”’%). At least one manufacturer provides a special kit for measurements from 10 to 100”’% CO2, but the normal 100”’cc hand pump is not used. See Note 1.

Note 1:High-range carbon dioxide detector tubes will have measuring ranges in percent (%) CO2, and low-range tubes will be in parts per million (ppm). To convert percent to ppm, multiply by 10”’000 (1”’%”’=”’10”’000 ppm).
