Analytical present the EPIC series quadrupole mass spectrometers specifically
designed with maximum flexibility for diverse processes and phenomena at UHV
and XHV pressure regimes, with measurement of neutrals, radicals and of both
positive and negative ions. Applications include temperature desorption monitoring
(UHV TPD), molecular beam analysis and laser reaction studies, together with
all of the functions of a high-performance residual gas analyser.
All systems feature pulsed ion counting detection for fastest measurement of
both positive ions and negative ions, the 200eV control of probe energy optimising
transmission of externally generated ions for maximum sensitivity and mass resolution.
Integral timers provide data acquisition gating for pulsed gas and pulsed ion
experiments with gating resolutions to 100 nanoseconds.
Ionisation of general vacuum and of molecular beam species is achieved with
a range of integrated electron bombardment ion sources. The scanning electron
energy facility enables precise investigation of appearance potentials and,
with the optional electron attachment mode, of electro-negative radical species.
The series includes mass range options to 1000amu, continuous 7-decade detection
from 1 to 10E+7 counts per second, precision three-stage mass filter and the
latest Hiden MASsoft Pro software suite with automated mass scale alignment.
Multiple scan modes facilitate measurement of external ion energies, 'soft ionisation'
studies and detector optimisation for plateau operation. High pressure operation
is addressed with the addition of differential pumping for operation at pressures
through to atmosphere.
