The estimation of carbon dioxide concentration in the presence of nitrous oxide, using a Lloyd-Haldane apparatus.

چکیده
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.

A simple method for the estimation of carbon dioxide concentration in the presence of nitrous oxide.
A modification of the Haldane technique, using potassium hydroxide as the absorbent, was devised to measure the concentration of carbon dioxide in the presence of nitrous oxide. It depends upon the principle that the amount of nitrous oxide absorbed is proportional to the duration of its exposure to the reagent. If the absorption of carbon dioxide from the gas mixture is completed within a fixe...
متن کاملEstimation of the Carbon Footprint in Dairy Sheep Farm
By 2050, the earth’s population is expected to be more than 9 billion. The need for secure food and water supply will force agriculture to increase production. The major greenhouse gases (GHGs) from the livestock sector are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) throughout the production process. These gases are the key contributor to an in...
متن کاملContinuous measurement of gas uptake and elimination in anesthetized patients using an extractable marker gas.
Measurement of pulmonary gas uptake and elimination is often performed, using nitrogen as marker gas to measure gas flow, by applying the Haldane transformation. Because of the inability to measure nitrogen with conventional equipment, measurement is difficult during inhalational anesthesia. A new method is described, which is compatible with any inspired gas mixture, in which fresh gas and exh...
متن کاملA paramagnetic method for measuring the carbon dioxide concentration of a gas.
A paramagnetic method of carbon dioxide analysis enables the simultaneous analysis of carbon dioxide and oxygen to be made at 2-min intervals. The method depends upon observing the change of oxygen concentration in a gas mixture before and after absorbing the carbon dioxide component. The carrier-gas in the experiments reported was nitrogen. The output of the paramagnetic meter was measured bot...

An increase in the emission of greenhouse gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) from the soil surface to the atmosphere has been of worldwide concern over the last several decades. Carbon dioxide is recognized as a significant contributor to global warming and climatic change, accounting for 60% of total greenhouse effect. The aim of this research was to dete...
