UHV
FTIR Spectroscopy

Why and when is the combination of ultra-high vacuum (UHV) and FTIR technique needed?

  • The research topic requires very precisely defined conditions (such as pressure, concentration, temperature etc.) to study model systems and better understand real processes.
  • The sample itself need to be cleaned, prepared, modified and/or kept under UHV conditions.
  • Other combined analysis techniques (such as XPS, LEED, TDS etc.) in interdisciplinary research projects need preferentially UHV conditions.
  • Not only UHV chambers, but also plasma chambers, high pressure chambers or other customized voluminous reaction chambers can be combined with FTIR technique.
  • Example spectra measured in a customer UHV chamber at the Institute of Functional Interfaces (IFG) in Karlsruhe Institute of Technology (KIT) showing the outstanding sensitivity of UHV-FTIR (with permission of Prof. Christof Wöll, director of IFG).

    FTIR spectroscopy can be added as a non-destructive and highly sensitive complementary analysis technique to a UHV facility or adapted to diverse customized chambers. Bruker’s VERTEX FTIR vacuum series research spectrometers VERTEX 80v and VERTEX 70v with complete vacuum optics layout provide superior sensitivity, stability and reproducibility in comparison to purged spectrometers, because the entire beam path can be evacuated to avoid atmospheric and environmental disturbance. Especially the VERTEX 80v vacuum spectrometer is the gold standard for high-end FTIR applications and UHV adaptions allowing to measure weak bands down to 10-5 au (absorbance units) and even beyond. Furthermore, the adaption of vacuum chambers with vacuum spectrometers is technically more efficient and reliable.

Bruker is highly experienced in this demanding application field and offers specialized UHV FTIR solutions. We have successfully installed adaptions for different UHV systems manufactured by various UHV suppliers. We are able to offer flexible solutions to adapt UHV chambers of different dimensions and designs.

To fully understand your application challenges and meet your individual experimental requirements we provide you the UHV FTIR Questionnaire to better express your need and enable smooth and efficient communication.
