Un sistema per l'analisi di ioni, neutri e radicali in studi di desorbimento in UHV

Misura ioni e neutri nel desorbimento stimolato da elettroni e neutroni

IDP è un sistema per l'analisi diretta di ioni a bassa energia prodotti da tecniche scientifiche di superficie in UHV. La applicazioni includono il desorbimento stimolato da elettroni e da fotoni e gli studi di desorbimento termico.


The Hiden EPIC and IDP have all the features of high performance RGAs - but with the addition of pole bias mid-axis potential and negative ion capability making them outstanding research grade mass spectrometers.

- Pulse Ion Counting Detector with continuous seven decade data presentation

- Direct observation of Positive / Negative ions, Radicals and Neutrals mass and yields

- 4 lens Ion Optics with integral electron ioniser and UHV compatible shroud

- Ion Energy distribution by mid-axis potential scanning ±100 V, 1000eV option

- High Sensitivity Triple filter Quadrupole, mass range options to 2500amu

- Signal gating 100 nano second resolution for energy & mass distributions vs time or TOF studies

- Temperature reading integrated into data displays for thermal desorption applications

- Stability (less than ±0.5% height variation over 24h)

- MASsoft control via RS232, USB or Ethernet LAN

The system is supplied with MASsoft 7 Professional Edition software.

This Windows 8 compatible software allows control of the instrument via USB 2.0, RS232 or Ethernet. Provides comprehensive I/O for data output and for reading data from external devices for integration and display with mass spectrometer data.
