NAP-XPS System with SPM and IRRAS

Near Ambient Pressure XPS with SPM and IRRAS Multimethod System for Deeper Surface Analysis

The combination of different analysis techniques allows for getting a deeper insight into the studied processes. Therefore SPECS has designed in which NAP-XPS with SPM and IRRAS allows for the combination of NAP-SPM or FTIR spectroscopy for deeper insight into the surface processes .

NAP-SPM technique is an excellent complementary tool to NAP-XPS. While NAP-XPS delivers information about the chemical composition of the sample surface, NAP-SPM  allows the user to get atomically resolved images of the studied surfaces under UHV conditions or in a specific gas atmosphere.

The SPM Aarhus NAP is perfectly suited to be incorporated into complex multimethod systems. Due to its excellent mechanical stability the SPM Aarhus NAP can deliver atomic resolution even when different system modules are in full operation. The below image shows an example of a system where the SPM Aarhus NAP is combined with a NAP-XPS and a preparation system module.

IR-spectroscopy is an established method for measuring the vibrational signature of a molecule. It can distinguish between molecules in the gas phase and adsorbed molecules on a surface on different sites. Therefore, IRRAS technique is extremely well suited for investigations of surfaces under a specific gas atmosphere and a widely-used complementary investigation method to NAP-XPS. Examples of NAP-XPS systems combined with IRRAS are shown in the pictures below.
