New mass spectrometers for UHV researchers

Hiden Analytical has introduced the Epic quadruple mass spectrometers.

The Epic mass spectrometers are designed for flexibility for diverse processes and phenomena at UHV and XHV pressure regimes.

They can measure neutrals, radicals and positive and negative ions.

Applications include temperature desorption monitoring (UHV TPD), molecular beam analysis and laser reaction studies, together with the functions of a high-performance residual gas analyser.

All systems feature pulsed ion-counting detection for fastest measurement of positive and negative ions.

The 200eV control of probe energy optimises the 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.

Integrated electron bombardment ion sources allow ionisation of general vacuum and of molecular beam species.

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 seven-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.
