The QGA - The New Gas Analyser from Hiden Analytical
(Nanowerk News) Hiden Analytical introduce the new QGA compact
benchtop mass spectrometer configured for
continuous real-time multi-species analysis of both
gases and vapours in the pressure range from 2 bar to
100mbar absolute. Applications include thermal
analysis, fermentation processes, catalysis and
general gas reaction studies.
With mass range to 300amu and detection levels to
100ppb the system features the QGA operating
program for quantitative analysis of up to 16 gases and
vapours, together with an internal 10-peak spectral library and automated spectral overlap correction. Data is readily
integrated in real time with external monitors including temperature, pressure and weight and with external gas
monitors for applications such as CO monitoring in the presence of N2. The innovative APSI mode reduces molecular
fragmentation by soft ionisation to refine analysis of complex organic molecules and enables selective ionisation of
many gas species by selection of specific ionisation energies - helium and deuterium at mass 4 for example.
Hiden QGA compact benchtop mass spectrometer.
The flexible 2M long sample interface operates to 200°C and is configured to balance sample consumption to the
process requirements with sample consumption rates controllable from 1 to 16 mL/min. Options include highpressure
adaptors for sample pressures to 30 bar, gas stream selectors for selection from up to 80 gas streams and
hot-zone extensions for direct sampling from processes to 1000°C.
