The carrier gas is supplied to the instrument at constant pressure from a cylinder.
Gaseous helium is used as a coolant during the drawing of optical fibers, as a carrier gas for chromatography, and as a leak detection gas in a variety of industries.
The carrier gas is generally supplied by compressed cylinders and the pressure of carrier gas is constant.
A carrier gas filter system is recommended to be installed on the Helium line (He).
The column was conditioned overnight at 180oC with a flow of nitrogen carrier gas. Operating conditions were:Oven temperature 100 or 130oC;Injection temperature 160 c;Nitrogen flow; 35ml/min;Hydrogen 28ml/min;Oxygen 100mL/min.
An aqueous caustic solution removes carrier gas impurities harmful to the detector cell.
The selection of chromatographic column, flow rate of carrier gas, column temperature, solvent, sample size and the column ratio of sample and solvent were experimented.
Degradation of methyl violet solution by gas-liquid gliding arc discharge under different carrier gases
UF/carrier gas compressors
Considering the very short particle residence time in the free-fall reactor, air was directly used as carrier gas to study the fast pyrolysis and sulfur evolution of coal under oxidizing atmosphere.
Operation parameters were examined when the discontinuous and continuous sample introduction systems with carrier gas N2 and continuous sample introduction system with carrier gas CO2 were used.
In fluid bed, both particles and carrier gas occur violent turbulence so that the heat transfer and mass transfer in the furnace are speeded.
For dense phase conveying of pulverized material there is a close relationship among many parameters, such as fluidization velocity, carrier gas flow rate, pipe diameter etc.
