dissolved oxygen concentration
1Winkler test for dissolved oxygen — The Winkler test is used to determine the level of dissolved oxygen in water samples. This metric is then used to estimate the biological activity in the water sample. An excess of Manganese(II) salt, iodide (I ) and hydroxide (OH ) ions are… …

3Oxygen saturation — or dissolved oxygen (DO) is a relative measure of the amount of oxygen that is dissolved or carried in a given medium. It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. It has… …
4Oxygen — This article is about the chemical element and its most stable form, O2 or dioxygen. For other forms of this element, see Allotropes of oxygen. For other uses, see Oxygen (disambiguation). nitrogen ← oxygen → fluorine ↑ O ↓ …

6Concentration cell — A concentration cell is a limited form of a galvanic cell that has two equivalent half cells of the same material differing only in concentrations. One can calculate the potential developed by such a cell using the Nernst Equation. A… …
7oxygen depletion — noun the reduction in the concentration of dissolved oxygen in water, especially as a result of pollution …
8Apparent oxygen utilisation — In freshwater or marine systems apparent oxygen utilisation (AOU) is the difference between the measured dissolved oxygen concentration and its equilibrium saturation concentration in water with the same physical and chemical properties [Garcia,… …
9Oxygen isotope ratio cycle — Oxygen isotope ratio cycles are cyclical variations in the ratio of the abundance of oxygen with an atomic mass of 18 to the abundance of oxygen with an atomic mass of 16 present in some substances, such as polar ice or calcite in ocean core… …
10Dissolved gas analysis — or DGA is the study of dissolved gases in insulating fluid. [1] Insulating materials within transformers and related equipment break down to liberate gases within the unit. The distribution of these gases can be related to the type of electrical… …
