| Abstract: | In the analysis of samples containing carbonates, some of the carbon dioxide liberated during the heating remains in the Penfield tube and interfers with determination. The error can be eliminated by passing a flow of air saturated with water vapour through the tube to displace the carbon dioxide. |
