The SPR flow cell is custom made for the Multiskop and optimized for the adsorption measurements. The cell utilizes the Kretschman configuration (excitation of surface plasmona via a prism). The design of prism clamp maximizes the accessible angle range of the reflection scans and ensures that the beam is not chopped off. 表面等離子共振儀(SPR)（Surface Plasmon Resonance）
