| Abstract: | The Coulometrics Inc. CO2 coulometer has been shown to be an accurate and reliable CO2 measuring device. The coulometric efficiency is essentially 100%. This means that the method can be considered as a standard reference method for CO2. As with a CO2 absorption tube, certain potential interferences must be considered, however, the removal of these interferences is well documented in the literature.The CO2 coulometer has found a variety of applications in the author's 3. effect of flow rate on absorption of CO2 by coulometer | CaCO3 (mg) | C (mg) | Flow rate (cm3/min) | C found (mg) | C (%) | | 27.989 | 3.359 | 100 | 3.3669 | 12.03 | | 28.604 | 3.432 | 200 | 3.4343 | 12.00 | | 29.259 | 3.511 | 300 | 3.5149 | 12.01 | | 33.808 | 4.057 | 400 | 4.0381 | 11.94 | | 5.629 | 0.675 | 500 | 0.6760 | 12.01 | | 10.311 | 1.237 | 500 | 1.2337 | 11.96 | | 15.647 | 1.878 | 500 | 1.8706 | 11.95 | | 35.214 | 4.226 | 500 | 4.1982 | 11.92 | | 40.733 | 4.888 | 500 | 4.8212 | 11.84 | | 59.678 | 7.161 | 500 | 7.0263 | 11.77 | | 30.386 | 3.646 | 780 | 3.5941 | 11.83 | | 29.781 | 3.574 | 780 | 3.5361 | 11.87 | | 28.113 | 3.374 | 1150 | 3.2534 | 11.57 |
