A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. complete blood type would describe a full set of 30 substances on the surface of RBCs, and an individual's blood type is one of many possible combinations of blood-group antigens.
Thus, cavitation is the name given to a mechanism in which vapor bubbles (or cavities) in a fluid grow and collapse due to local pressure fluctuations. These fluctuations can produce a low pressure, in the form of vapor pressure of the fluid.
The mobile phase in gas chromatography is an inert (nonreactive) gas, usually helium or nitrogen. This mobile phase is often called the carrier gas. The retention time is the time (in seconds or minutes) between the injection of a sample and the top of a peak of a component of the sample.These times are used like R f values in TLC, to establish the identity of the compound giving the peak by comparison.his mobile phase is often called the carrier gas.
