APXPS – near atmospheric pressure XPS instruments provide for XPS analysis on surfaces at higher pressures, and closer to real world environment than UHV. Hiden’s range of quadrupole mass spectrometers are coupled to the high pressure sample cell for analysis of the gas.

APXPS – near atmospheric pressure XPS instruments provide for XPS analysis on surfaces at higher pressures, and closer to real world environment than UHV. The surface structures may be different when analysed at atmospheric pressure compared to observations made with traditional XPS at UHV. Dynamic effects from gas reactions could be important , and together with the Hiden mass spectrometer system, the results can be directly correlated with the XPS data.
