These are the same compounds referred to as Volatile Organic Compounds ( VOC ) and usually determined by Purge and Trap Gas Chromatography.

Gas is usually the deepest in the pattern, and can alternate with oil.

Gas emissions may be monitored with equipment including portable ultra-violet spectrometers ( COSPEC, now superseded by the miniDOAS ), which analyzes the presence of volcanic gases such as sulfur dioxide ; or by infra-red spectroscopy ( FTIR ).

In the case of n-type Gas doping, hydrogen sulfide is passed over the gallium arsenide, and sulfur is incorporated into the structure.

* Flue Gas Treatment article including the removal of hydrogen chloride, sulfur trioxide, and other heavy metal particles such as mercury.

The project which took three million man-hours to design and 70 million man-hours to construct, brought with it the latest technological advancements to increase operational efficiency as well as environmental safety, from an onshore smokeless flare system to a new, 99 % effective sulfur recovery system at Berri Gas Plant that uses technology to make it the cleanest operating plant of all Saudi Aramco facilities.

Gas in the breathing circuit is at ambient pressure, and stored gas is provided through regulators or injectors, dependent on design.

Gas ( SF < sub > 6 </ sub >) circuit breakers sometimes stretch the arc using a magnetic field, and then rely upon the dielectric strength of the SF < sub > 6 </ sub > to quench the stretched arc.

Gas chromatography ( GC ), also sometimes known as Gas-Liquid chromatography, ( GLC ), is a separation technique in which the mobile phase is a gas.

* Gas turbines are sometimes referred to as turbine engines.

Gas ovens often have a separate compartment for broiling, sometimes a drawer below the bottom flame.

Gas stations abandoned during the fuel crisis in the winter of 1973-74 were sometimes used for other purposes.

Gas chromatography is also sometimes known as vapor-phase chromatography ( VPC ), or gas – liquid partition chromatography ( GLPC ).

Such crossovers may sometimes involve the real actors — for example, a sketch on Royal Canadian Air Farce saw Yasir and Sarah from Little Mosque on the Prairie buying the gas station from Corner Gas, with all characters in the sketch being portrayed by the shows ' real actors — although they may also feature one genuine star from the show amid a cast comprised otherwise of the sketch show's own stable of actors.

Dinky Poore is the smallest ( and most sarcastic ) of the Mad Scientists ; this is sometimes relevant to the stories, as in " The Great Gas Bag Race ", in which the boys prepare to compete in a hot-air balloon race without deciding which two Mad Scientists will have the honor of crewing the balloon ; since Dinky weighs less than anyone else in the club, he is the only one who is certain of being chosen.

The tanks, which sometimes leaked, made the area undesirable, as did the Gas House Gang and other predators who operated in the area.

This torque provides better capacity for payloads including Gas Jerrycans which require sometimes enhanced suspension, and sturdy roofracks.

In the United States, valve connections are sometimes referred to as " CGA connections ," since the Compressed Gas Association ( CGA ) publishes guidelines on what connections to use for what products, e. g., In the United States, an argon cylinder will have a CGA 580 connection on the valve.

Gas cylinders are often color coded, but the codes are not standard across different jurisdictions, and sometimes are not regulated.

Gas injection through a porous anode ( transpiration cooling ) not only feeds back the energy transferred to the anode by the above mentioned processes, but also modifies the conditions in the arc itself.

Gas metal arc welding ( MIG welding )

Gas metal arc welding ( GMAW ), also known as metal inert gas or MIG welding, is a semi-automatic or automatic process that uses a continuous wire feed as an electrode and an inert or semi-inert gas mixture to protect the weld from contamination.

Gas tungsten arc welding ( GTAW ), or tungsten inert gas ( TIG ) welding, is a manual welding process that uses a nonconsumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material.

Gas metal arc welding

Gas metal arc welding ( GMAW ), commonly called MIG ( for metal / inert-gas ), is a semi-automatic or automatic welding process with a continuously fed consumable wire acting as both electrode and filler metal, along with an inert or semi-inert shielding gas flowed around the wire to protect the weld site from contamination.

Gas tungsten arc welding ( GTAW ), or tungsten / inert-gas ( TIG ) welding, is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material.

Gas tungsten arc welding, after decades of development, was finally perfected in 1941 and gas metal arc welding followed in 1948, allowing for fast welding of non-ferrous materials but requiring expensive shielding gases.

Gas tungsten arc welding ( GTAW ), also known as tungsten inert gas ( TIG ) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld.

Gas tungsten arc welding, because it affords greater control over the weld area than other welding processes, can produce high-quality welds when performed by skilled operators.

Gas tungsten arc welding uses a constant current power source, meaning that the current ( and thus the heat ) remains relatively constant, even if the arc distance and voltage change.
