DissolvedGasAnalysis or DGA is the study of dissolved gases in transformer oil. It is the most sensitive and reliable technique which gives an early indication of abnormal behavior of a transformer .DGA is advanced tool to diagnose the health of a transformer under Preventive Maintenance Programme. DGA consists of three steps. They are, sampling of transformer oil in an airtight glass tube, complete extraction of gases from the sample and subsequent analysis of the extracted gases for their quantity and combination. Transformer Oil Transformer oil is used as a coolant and insulator in a transformer. It baths every internal component and contains a lot of diagnostic information in the form of dissolved gases . Since these gases reveal the faults of a transformer, they are known as Fault Gases. They are formed in transformer oil, due to natural ageing and as a result of faults inside the transformer. Formation of fault gases is due to oxidation , vaporization , insulation decomposition , oil breakdown and electrolytic action.

orphan date January 2010 Evolved gasanalysis EGA is a method used to study the gas evolved from a heated sample that undergoes decomposition or desorption. It is possible to detect which gas is evolved using evolved gas detection EGD .

Breath gasanalysis is a method for gaining non invasive information on the clinical state of an individual by monitoring volatile organic compound s present in the exhaled breath . Breath gas concentration can then be related to blood concentrations via mathematical modeling as for example in blood alcohol testing.

The dissolved load contributes to the total amount of material removed from a Drainage basin catchment .

Dissolved air flotation DAF is a water treatment process that clarifies wastewater s or other waters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device. ref name Aqueous cite book author Beychok, Milton R. title Aqueous Wastes from Petroleum and Petrochemical Plants edition 1st publisher John Wiley & Sons year 1967 id Library of Congress Control Number LCCN 67019834 ref ref cite book author Lawrence K.

Wikibooks School Science Winkler test for dissolved oxygen The Winkler test is used to determine the concentration of dissolved oxygen in water samples. Dissolved Oxygen, abbreviated D.O., is widely used in water quality studies and routine operation of water reclamation facilities. An excess of manganese II salt, iodide I and hydroxide HO sup sup ions are added to a water sample causing a white precipitate of Mn OH sub 2 sub to form. This precipitate is then oxidized by the dissolved oxygen in the water sample into a brown manganese precipitate. In the next step, a strong acid either hydrochloric acid or sulfuric acid is added to acidify the solution. The brown precipitate then converts the iodide ion I to iodine . The amount of dissolved oxygen is directly proportional to the titration of iodine with a thiosulfate solution. ref name Numako cite journal author Chiya Numako and Izumi Nakai title XAFS studies of some precipitation and coloration reaction used in analytical chemistry journal Physica B Condensed Matter volume 208 209 pages 387 388 year 1995 doi 10.1016 0921 4526 94 00706 ... in 1888, this was a way for him to obtain his doctorate.

unreferenced date October 2009 Dissolved organic carbon DOC is a broad classification for organic molecule s of varied origin and composition within aquatic systems. The dissolved fraction of organic carbon is an operational classification. Many researchers use the term dissolved for concentrations below 0.45 micrometer s, but 0.22 micrometers is also common, saving colloid al for higher concentrations. DOC in marine and freshwater systems is one of the greatest cycled reservoirs of organic matter on Earth. The source of DOC depends on the body of water. In general, organic carbon compounds are a result of decomposition processes from dead organic matter such as plants. When water contacts highly organic soils, these components can drain into rivers and lakes as DOC. DOC is also extremely important in the transport of metal s in aquatic systems. Metals form extremely strong Coordination complex complexes with DOC, enhancing metal solubility while also reducing metal bioavailability . Significance DOC is a food supplement, supporting growth of microorganism s. Moreover it is an indicator of organic loadings in streams, as well as supporting terrestrial processing e.g., within soil, forests, and wetlands of organic matter. Dissolved organic carbon has a higher biodegradable dissolved organic carbon BDOC in first order streams compared to second order streams. In the absence of extensive wetland s, bog s, or swamp s, baseflow concentrations of DOC in undisturbed watersheds generally range from approximately 1 to 20 mg L carbon. Carbon concentrations considerably vary across ecosystems. For example, the Everglades may be near the top of the range and the middle of oceans may be near the bottom. Occasionally, high concentrations of organic carbon indicate anthropogenic influences ... regrowth within water distribution systems.

Colored dissolved organic matter CDOM is the optically measurable component of the dissolved organic matter in water. Also known as chromophoric dissolved organic matter, yellow substance , and gelbstoff , CDOM occurs naturally in aquatic environments primarily as a result of tannin stained waters tannins released from decaying detritus . CDOM most strongly absorbs short wavelength light ranging from blue to ultraviolet , whereas pure water absorbs longer wavelength red light. Therefore, non turbid water with little or no CDOM appears blue. The color of water will range through green, yellow green, and brown as CDOM increases. Significance of CDOM CDOM can have a significant effect on biological activity in aquatic systems. CDOM diminishes light as it penetrates water. This has a limiting effect on photosynthesis and can inhibit the growth of phytoplankton populations, which form the basis of oceanic food chains and are a primary source of atmospheric oxygen . CDOM also absorbs harmful UVA B radiation, protecting organisms from DNA damage. Absorption of UV radiation causes CDOM to bleach , reducing its optical density and absorptive capacity. This bleaching photodegradation of CDOM produces both low molecular weight organic compounds which may be utilized by microbes, and reactive oxygen species, which may damage tissues and alter the bioavailability of limiting trace metals. CDOM also interferes with the use of satellite spectrometer s to remotely estimate phytoplankton population distribution. As a byproduct of photosynthesis, chlorophyll is a key indicator of phytoplankton activity. However, CDOM and chlorophyll both absorb in the same spectral range so it is difficult to differentiate between the two. Although variations in CDOM are primarily the result of natural processes, human activities such as logging, agriculture, effluent discharge, and wetland drainage can ....
