1Column chromatography — A chemist in the 1950s using column chromatography. The Erlenmeyer receptacles are on the floor. Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds. It is often used for… …
2Flow show — A Flow show is a device on a drilling rig that is attached to the flow line and has a paddle that swings out as the flow of drilling fluid passes by it. The angle of the paddle increases as the volume of drilling fluid increases and pushes it out …
3column chromatography — Chem. See under chromatography. * * * ▪ chemistry in analytical chemistry, method for separating mixtures of substances in which a liquid or gaseous solution of the mixture is caused to flow through a tube packed with a finely divided solid …
4Monolithic HPLC column — A monolithic HPLC column is a special type of column used in HPLC with porous channels rather than beads. High performance liquid chromatography (HPLC) is the third most widely used laboratory instrument, surpassed only by analytical balances and …
5Balanced flow — In atmospheric science, balanced flow is an idealisation of atmospheric motion. The idealisation consists in considering the behaviour of one isolated parcel of air having constant density, its motion on a horizontal plane subject to selected… …
6pyroclastic flow — ALASKA VOLCANO OBSERVATORY GLOSSARY A dense, hot, chaotic avalanche of rock fragments, gas, and ash that travels rapidly away from an explosive eruption column, down the flanks of the volcano (synonymous with ash flow ). Pyroclastic flows move at …
7Electroosmotic flow — (or Electro osmotic flow, often abbreviated EOF) is the motion of liquid induced by an applied potential across a capillary tube or microchannel. Electroosmotic flow is an essential component in chemical separation techniques, notably capillary… …
8Eruption column — over Mount Pinatubo in the Philippines An eruption column consists of hot volcanic ash emitted during an explosive volcanic eruption. The ash forms a column rising many kilometres into the air above the peak of the volcano. In the most explosive… …
9Pyroclastic flow — Pyroclastic flows sweep down the flanks of Mayon Volcano, Philippines, in 1984 …
10Power flow study — In power engineering, the power flow study (also known as load flow study) is an important tool involving numerical analysis applied to a power system. Unlike traditional circuit analysis, a power flow study usually uses simplified notation such… …
