QGA quantitative gas analysis package
07-11-2013
Mass spectrometer spectral fragmentation patterns can complicate analysis of gas mixtures due to samemass
contributions from multiple species. The new Hiden QGA Professional gas/vapour analysis software
provides real-time continuous and quantitative analysis of gas mixtures comprising up to 16 species and is
now available for operation with all Hiden gas analysis systems.
The integral, user expandable spectral library details each species with up to 10 mass fragmentation
peaks. These are used by the integral calculator to compile a preview composite of a specified gas mixture
to automatically select the optimum masses for measurement and for deconvolution, together with onscreen
colour simulation of relative same-mass contributions and species-specific mass peaks. The
relative abundance of each species is user variable to determine practical detection limits, which extend
down to 0.1ppm. Inputs provide for import and data integration of external parameters such as
temperature, process pressure, weight. External gas monitor measurement, CO for example, can be
integrated directly with the mass spectrometer data.
The system provides for multistream analysis with automatic stream sequencing and with a capacity of 80
streams. Up to four streams can be simultaneously displayed graphically on-screen in real time.
