Organic vapour jet printing ( OVJP ) uses an inert carrier gas, such as argon or nitrogen, to transport evaporated organic molecules ( as in organic vapour phase deposition ).

Argon may be used as the carrier gas in gas chromatography and in electrospray ionization mass spectrometry; it is the gas of choice for the plasma used in wafer cleaning in microfabrication.
33.
Uniform films can be grown by reducing the carrier gas pressure, which will increase the velocity and mean free path of the gas, and as a result boundary layer thickness decreases.
34.
Pyrolytic systems can support a middle range of flow but have a difficult time with very low flow rates and low steam to hydrogen ratios when adding water vapor to a carrier gas.
35.
This makes the detector sensitive to the mass rather than the concentration, which is useful because the response of the detector is not greatly affected by changes in the carrier gas flow rate.
36.
This occurs because the carrier gas becomes saturated with the vapors of the organic material coming out of the source and then moves towards the cooled substrate, Fig . 6 ( b ).

The quality of this steam added to the carrier gas is a function of the water temperature, carrier gas temperature, height of the liquid head, and pressure of the carrier gas.

As the carrier gas sweeps the analyte molecules through the column, this motion is inhibited by the adsorption of the analyte molecules either onto the column walls or onto packing materials in the column.
