Analytical introduce a family of quadrupole mass spectrometers designed
specifically for UHV/XHV performance, evolved from the Hiden 3F-series concept
and incorporating the proven triple-stage mass filter technology for optimum
mass separation, ion transmission efficiency and contamination resistance.
Pulse ion counting detection is common throughout this series for
highest sensitivity and fastest response times, with choice of
only or combined positive and negative ion detection.
Quadrupole mean energy scanning is featured for systems configured
for analysis of externally generated ions, enabling ion energy
distribution measurement and optimisation for neutrals analysis.
All systems feature the Windows-MASsoft Pro control program with
multi-parameter scanning for optimisation of operating parameters for
each individual mass channel. Ion detection is by fast pulse counting
with continuous 7-decade scaling from 1c/s to 10E+7c/s. Sampling
rates exceed 500 measurements per second, with partial pressure
detection down to 5x10E-15 mbar and trace level detection to 5ppb.
A choice of ionisation sources enables system optimisation for varied
applications including molecular beam, laser ablation, thermal desorption and general neutrals studies. All
ion source parameters are software controlled with modes for ion attachment, ‘soft’ ionisation and
appearance potential measurement.
