TERM DEFINITION
C3H6 The molecular formula for Propylene.
C3H8 The molecular formula for Propane.
C4H10 The molecular formula for Butane.
C4H8C The molecular formula for Butylene.
C5+ A standard abbreviation for Pentanes Plus (IC5, NC5 and C6+).
C5H12 The molecular formula for Pentane.
C6+ A standard abbreviation for Hexane Plus.
C6H14 The molecular formula for Hexane.
C7H16 The molecular formula for Heptane.
C8H18 The molecular formula for Octane.
C9H20 The molecular formula for Nonane.
Cache Memory Fast memory used to improve the performance of a CPU. Instructions that will
soon be executed are placed in cache memory shortly before they are needed.
This process speeds up the operation of the CPU.
Calibrate To ascertain, usually by comparison with a standard, the locations at which
scale or chart graduations should be placed to correspond to a series of values
of the quantity which the instrument is to measure, receive or transmit. Also, to
adjust the output of a device, to bring it to a desired value, within a specified
tolerance for a particular value of the input. Also, to ascertain the error in the
output of a device by checking it against a standard.
Calorie The quantity of thermal energy required to raise one gram of water 1°C at 15°C.
Calorimeter An apparatus which is used to determine the heating value of a combustible
material.
Capacitor An electronic component that stores electrical charge.
Capacity The total number of ampere-hours (or watt-hours) that can be withdrawn from a
cell/battery under specified conditions of discharge.
CAR Carrier Gas (located on NGC8200 series Feed-Through Assembly).
Carbon Base of all hydrocarbons and is capable of combining with hydrogen in many
proportions, resulting in numberless hydrocarbon compounds. The carbon
content of a hydrocarbon determines, to a degree, the hydrocarbon's burning
characteristics and qualities.
Carbon Dioxide Colorless, odorless and slightly acid-tasting gas, consisting of one atom of
carbon joined to two atoms of oxygen. C02. Produced by combustion or
oxidation of materials containing carbon. Commonly referred to as dry ice when
in its solid form.
Carrier Gas Totalflow recommends that Helium be used as a carrier gas. Carrier gas is
used in the “Mobile Phase” of chromatography, pushing the sample gas
through the columns (“Stationary Phase”). Because Helium has no heating
value, it does not affect the Btu values.
Casinghead Gas Natural gas that is produced from oil wells along with crude oil.
Catalyst A substance that speeds up a chemical reaction without being consumed itself
in the reaction. A substance that alters (usually increases) the rate at which a
reaction occurs.
Catalytic The process of altering, accelerating or instigating a chemical reaction.
Cathode An electrode through which current leaves any nonmetallic conductor. An
electrolytic cathode is an electrode at which positive ions are discharged, or
negative ions are formed, or at which other reducing reactions occur. The
negative electrode of a galvanic cell; of an electrolytic capacitor.
