Gas Phase SPR allows SPR analysis to be carried out at solid-gas interfaces.
Gas phase SPR capability is sensitive to biomolecular processes occurring at the solid-gas interface. By coating a metal film with sensing materials such as polymers (Figure 1), adsorption of the molecules onto the sensing materials can be detected by observing SPR angle shift.
This technology is designed to provide users with a highly sensitive, fast and easy-to-use tool to study various molecular binding processes onto a solid surface from the gas phase. The system is equipped with a gas flow cell with fittings that are ready to connect to gas or chemical vapor sources. This helps to facilitate chemical vapor detection and gas-phase chemical sensor development.
