The phrase "active gaseous" is correct and usable in written English.
It can be used in scientific or technical contexts to describe a state of matter that is both active and in a gaseous form, often relating to chemistry or physics.
Example: "The experiment required the use of active gaseous compounds to observe the reaction rates."
Alternatives: "reactive gas" or "dynamic gas phase".
Rapid-scan IR spectroscopy was used to quantify the IR-active gaseous products in real time, while mass spectrometry was used to identify N2 and, in two cases, O2.
Tail free short laser pulses were generated by employing a nitrogen lean gaseous active medium.
A characterisation of a system designed for active sampling of gaseous compounds with Solid Phase Microextraction (SPME) fibres is described.
At low O2 concentration no gaseous active chlorine was determined, while a significant amount was measured in the presence of oxygen.
A detector with a gaseous active media equipped with gas electron multiplier (GEM) technique will be employed to measure tracks of charged particles at forward direction in order to achieve a high momentum resolution.
The advent of the fast-valve device, described previously, permits measurement of molecular-flow times of chemically active or inactive gaseous species through radioactive ion beam (RIB) target ion source systems, independent of size, geometry and materials of construction.
NOx and O3 were detected as the main gaseous plasma active molecules, with the NOx concentration being an increasing function of the applied voltage and air flow rate.
These active complexes could react with gaseous NO to produce N2 and H2O.
It is characterized by high temperature (1000 1050 °C), and higher concentrations of gaseous species normally active in coke formation.
In addition, the defects on the surface of rGO, including oxygen functional groups, can act as active sites for interaction with gaseous molecules.
