IDP / IDP 1000 Series

The Hiden IDP Probe is a quadrupole mass spectrometer system configured with ion optics, ion extraction lens and integral electron impact ion source.

Applications

The Hiden IDP is for the direct analysis of low energy ions and neutrals from UHV surface science techniques. Applications include electron stimulated desorption, photon stimulated desorption and thermal desorption studies.

Additionally the system can be used as a high sensitivity residual gas analyser at UHV pressures.

Hiden IDP systems are directly PC controlled, Windows® MASsoft Professional PC software is included as standard and provides comprehensive data acquisition and presentation routines.

The Hiden IDP probe features

• Mass Range options 50 amu, 300 amu, 510 amu, 1000 amu, and 2500 amu.
• Ion counting detection – positive and negative ion.
• 7 decade detector 1 to 107 c/s with continuous seven decade data presentation.
• Integral IDP ion optics.
• Integral UHV compatible analyser shroud.
• Temperature reading integrated into data displays for thermal desorption applications.
• Peak Integration with base line subtraction for desorption profile analysis.
• Direct pulse rate output as a TTL signal.
• External pulse gating input.
• Windows® MASsoft Professional PC software with RS232 and Ethernet communication links.

IDP 1000 Operating Modes include

• Systems include pre-set software modes for Leak detection, Trend analysis, Histogram scan and Profile peak scan with 0.02 amu increment over a user selectable mass window.
• Background subtraction, providing subtraction of a designated spectrum from real time acquired data. Background subtraction operates for Histogram scans, Trend Analysis, Leak detection and Profile peak scans.
• Trend analysis with real time plotting of peak intensities on a time axis, with tabular and graphical data views plotted simultaneously. Up to 100 mass channels can be programmed.
• Peak Integration with base line subtraction providing integration of user selectable desorption profiles from trend analysis data.
• Each mass channel in a trend analysis can have its own mass spectrometer parameter set for optimising the acquisition for each species.
• Trend analysis channels are automatically set up by a simple double click selection on the required species names from the on board library list or they can be manually selected by typing the required mass number and species name.
• Socket Interface for application control and dynamic data link with Windows® compliant applications.
• Map mode for continuous display of mass selected ion intensity as a function of selected ion source parameters.
• Electron energy scanning of a mass selected ion intensity for determination of appearance potentials and differentiation of radicals from a parent stable neutral molecule.
• Quadrupole mid-axis potential scanning in the range -100 V to +100 V for retarding field energy analysis.
• Mixed mode scanning. A user editable scan generator enables customisable data acquisition and multi window data displays including user selected views of profile peak, trend analysis (tabular and graphical), and histogram data simultaneously.
•  Automatic tuning and on-line manual tuning of all ion source parameters under slide bar control.
• Review and compare historical data simultaneously with real time data.
• Data export facilities to ASCII files and Windows® supported output devices.
• An integral ‘events’ program provides a user editable interface to link data to the integral input/output subsystem.
