Gas analysers suit diverse vacuum applications
Hiden Analytical
Quadrupole residual gas analysers
Hiden Analytical now offers an extended range of quadrupole residual gas analysers for diverse vacuum applications through the pressure range from millibar through to extreme high vacuum (XHV).
The company's regular systems are supplemented by a custom-engineering design facility for experiment-specific requirements, including in-vacuum cooling and heating, probe insertion distance and remote in-vacuum mounting.
Typical mass ranges of 1:50amu to 1:300amu accommodate most gaseous and vapour species, with alternative mass ranges to 1000amu offered for specialised applications.
Analogue and pulse ion-counting detectors are available to optimise performance for a wide dynamic range, a measurement rate of up to 500 samples per second and a sensitivity of up to 5x10E-16 millibar.
The single-stage mass filters are suitable for many general applications, with the 3F-series triple-stage mass filter being suitable for the most demanding applications, requiring maximum performance in terms of both mass resolution and abundance sensitivity.
All operating parameters are software integrated, giving full control of mass resolution, ionisation current and ionisation energies, with the soft ionisation feature being used for simplification of complex molecular fragmentation spectra.
Ion source options are configured for general analysis, for molecular-beam applications or for minimal degas rates for UHV/XHV applications.
