Gases can dissolve in another solute including other gases or liquids, although often synonymous with a gas-liquid mixture, where the dissolved amount and rate depends on its subjected pressure, temperature, and the interaction between the molecules of both substances.
Dissolved gas measurements can be used in a wide variety of applications including monitoring a patient health, observing the respiration of fishes, and studying photosynthesis of marine plants. Life science studies often measure the amount of dissolved oxygen, carbon dioxide and nitrogen in aqueous solutions. Additionally, there are many methods to detect and record the amount of dissolved gases, including conventional membrane-covered electrochemical sensors, optical sensors and galvanic sensors.
