462:– Gas is forced through a semi-permeable membrane by a pressure difference. Some of the constituent gases pass through the membrane more easily than the others, and the output from the low pressure side is enriched with the gases which pass through more easily. Gases which are slower to pass through the membrane accumulate on the high pressure side and are continuously discharged to retain a steady concentration. The process may be repeated in several stages to increase concentrations.

174:. The oxygen is usually the only metabolically active component unless the gas is an anaesthetic mixture. Some of the oxygen in the breathing gas is consumed by the metabolic processes, and the inert components are unchanged, and serve mainly to dilute the oxygen to an appropriate concentration, and are therefore also known as diluent gases.
241:. Part of the operation of the life-support system is the replenishment of oxygen used by the occupants, and removal of the carbon dioxide waste product by the gas conditioning unit. This entails monitoring of the composition of the chamber gas and periodic addition of oxygen to the chamber gas at the internal pressure of the chamber.

Span gases are used for testing and calibrating gas detection equipment by exposing the sensor to a known concentration of a contaminant. The gases are used as a reference point to ensure correct readings after calibration and have very accurate composition, with a content of the gas to be detected

The mole fraction is also called the amount fraction, and is the number of molecules of a constituent divided by the total number of all molecules in the mixture. For example, a 50% oxygen, 50% helium mixture will contain approximately the same number of molecules of oxygen and helium. As both

Batch gas blending requires the appropriate amounts of the constituent gases to be measured and mixed together until the mixture is homogeneous. The amounts are based on the mole (or molar) fractions, but measured either by volume or by mass. Volume measurement may be done indirectly by partial

The gravimetric method uses sensitive and accurately calibrated scales to weigh the amounts of gases added into the cylinder. Precise measurement is required as inaccuracy or impurities can result in incorrect calibration. The container for calibration gas must be as close to perfectly clean as

Constant mass flow supply: Precision mass flow controllers are used to control the flow rate of each gas for blending. Mass flow meters may be installed on the outputs of the mass flow controllers to monitor the output. The gases may be passed through a static mixer to ensure homogeneous
334:
After filling, the gas mixture must be thoroughly mixed to ensure that all components are evenly distributed throughout the container to prevent possible variations on composition within the container. This is commonly done by rolling the container horizontally for 2 to 4 hours.
394:
Mass fraction blending is used where great accuracy of the mixture is critical, such as in calibration gases. The method is not suited to moving platforms where the accelerations can cause inaccurate measurement, and therefore is unsuitable for mixing diving gases on vessels.
356:
oxygen and helium approximate ideal gases at pressures below 200 bar, each will occupy the same volume at the same pressure and temperature, so they can be measured by volume at the same pressure, then mixed, or by partial pressure when decanted into the same container.
127:: An inert gas such as nitrogen is bubbled through the wine, which removes the dissolved oxygen. Carbon dioxide is also removed and to ensure that an appropriate amount of carbon dioxide remains, a mixture of nitrogen and carbon dioxide may be used for the sparging gas.
376:
Partial pressure blending is commonly used for breathing gases for diving. The accuracy required for this application can be achieved by using a pressure gauge which reads accurately to 0.5 bar, and allowing the temperature to equilibrate after each gas is added.
372:
Also known as volumetric blending. This must be done at constant temperature for best accuracy, though it is possible to compensate for temperature changes in proportion to the accuracy of the temperature measured before and after each gas is added to the mixture.

Shielding gases are inert or semi-inert gases used in gas metal arc welding and gas tungsten arc welding to protect the weld area from oxygen and water vapour, which can reduce the quality of the weld or make the welding more difficult.

Continuous gas blending is used for some surface supplied diving applications, and for many chemical processes using reactive gas mixtures, particularly where there may be a need to alter the mixture during the operation or process.

Purging and blanketing: The removal of oxygen from the headspace above the wine in a container by flushing with a similar gas mixture to that used for sparging is called purging, and if it is left there it is called blanketing or

for a specific purpose where the composition of the resulting mixture is specified and controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.
477:
Gas mixtures must generally be analysed either in process or after blending for quality control. This is particularly important for breathing gas mixtures where errors can affect the health and safety of the end user.
301:
Protective gas mixtures may be used to exclude air or other gases from the surface of sensitive materials during processing. Examples include melting of reactive metals such as magnesium, and heat treatment of steels.

Constant flow blending – a controlled flow of the constituent gases is mixed to form the product. Blending may occur at ambient pressure or at a pressure setting above ambient but lower than supply gas pressures.
