UHV Surface Analysis Systems
For the determination of surface composition, contaminant analysis and for depth profiling
Hiden Analytical designs some of the world’s highest sensitivity mass spectrometers for critical vacuum processes in both extreme- and ultra-high vacuum conditions (XHV/UHV). With outstanding detection capabilities provided, including pulse ion counting, Hiden mass spectrometers offer the most sensitive detection limits and fast data acquisition for applications in XHV/UHV surface science, UHV-TPD, and secondary ion mass spectrometry (SIMS).
UHV conditions extend much lower (10-7 – 10-12 mbar), while the XHV range extends further still (<10-12). In these environments, the dominant molecular species present are those that have desorbed from the chamber walls, and extremely light molecules like hydrogen. To put these into context, UHV conditions are exploited for high-energy physics and nuclear research while XHV is characteristic of pressure levels observed in outer-space.
UHV Surface Science with Hiden Analytical
Consequently, UHV surface science demands stringent attention to the finest details. Hiden Analytical mass spectrometers provide extremely high sensitivity detection capabilities for both positive and negative ion detection through seven continuous decades, with an integral accumulation mode for acquiring discreet particle events. With special configurations available upon request, including distinct gating inputs and multi-channel analysis MCA modes, Hiden mass spectrometers can satisfy the demands of numerous XHV/UHV testing methods. These include:
FIB – SIMS | Focussed Ion Beam Secondary Ion Mass Spectrometry
Mass Spectrometers for Residual Gas Analysis – RGA | For Applications in a Vacuum Environment
EPIC | Quadrupole Mass Spectrometer for Scientific Applications
Hiden IDP Quadrupole Mass Spectrometer for low energy ion analysis in electron or photon stimulated ion desorption studies
Hiden TPD Workstation | A complete experimental system for UHV temperature programmed desorption (TPD) studies
