The phrase "a range of gas" is correct and usable in written English.
It can be used when referring to various types or quantities of gas, often in scientific or technical contexts.
Example: "The experiment required a range of gas samples to analyze the chemical reactions."
Alternatives: "a variety of gas" or "a selection of gas".
A range of gas flow rates, temperatures and butane concentrations were tested.
Results are presented that demonstrate the suitability and consistency of the method for a range of gas mixing levels.
The rate of bubble coalescence downstream of this baffle was determined, over a range of gas hold-up.
Experiments were conducted at high pressure over a range of gas and liquid velocities and different bed characteristics.
Residence time distribution (RTD) studies were conducted for a range of gas flow rates chosen to span the dispersed flow bubble regime.
The performance of the system was tested via simultaneous collection of a range of gas and particle samples of ethylbenzene, xylenes, n-alkanes, polycyclic aromatic hydrocarbons, and monoterpenes.
Different configurations and orientations of the novel nozzle design were considered over a range of gas-to-liquid flow rate ratios (GLR) from 0.00031 to 0.00204.
Although the correlations proposed in Eqs. 8, 9 are based upon the gas gravity of the natural gas systems presented in Table 1, it can be noticed that the range of gas gravity of considered systems (Table 1) covers a range of gases typically seen in petroleum reservoir.
