Ventilation measurement using gas-chromatographic analysis of sulphur hexafluoride. Ventilationsmatning med gaskromatografisk analys av svavelhexafluorid.

Describes use of SF6 in tracer gas studies to determine solvent fumes in indoor and outdoor environments and how meteorological conditions affect SO2 content of atmosphere. Lists instrumentation used. Discusses properties of SF6 and properties required of a tracer gas, calibration and comparison of U.S. and Swedish results. Lists practical problems both general and specific to gas chromatography and factors affecting results. Suggests future development prospects stating advantage that lower concentrations of SF6 are required compared with N2O for examples.
