The estimation of carbon dioxide concentration in the presence of nitrous oxide, using a Lloyd-Haldane apparatus
Abstract:
A method of gas analysis is described for estimating carbon dioxide in the presence of nitrous oxide, using a modified Lloyd-Haldane apparatus. Some of the sample, after scrubbing with soda-lime, bubbles through the potash and this eliminates the solubility effect of nitrous oxide by equilibrating the standard potash solution with nitrous oxide at the tension of the sample analysed and eliminating absorption of nitrous oxide from the burette. The results show close agreement with another apparatus and method based on different principles. The method is absolute, requiring neither empirical nor theoretical correction.
